In this PR, paras module emit runtime events on certain PVF pre-checking
related conditions.

Specifically, there are 3 new events in the paras module:

1. PvfCheckStarted
2. PvfCheckAccepted
3. PvfCheckRejected

All of those have identifiers for the parachain that triggered the PVF
pre-checking and the validation code that goes through the pre-checking.

The mechanics of those are as follows. Each time a new PVF is added, be
it due to onboarding or upgrading, the `PvfCheckStarted` will be
triggered. If another parachain triggers a pre-checking process for the
validation code which is already being pre-checked, another
`PvfCheckStarted` event will be triggered with the corresponding para
id.

When the PVF pre-checking voting for a PVF was finished, several
`PvfCheckAccepted/Rejected` events will be triggered: one for each para id that
was subscribed to this check (i.e. was a "cause" for it).

If the PVF pre-checking is disabled, then one can still expect these
events to be fired. Since insta PVF approval is syncronous, the
`PvfCheckStarted` will be followed by the `PvfCheckAccepted` with the
same validation code and para id.

If somebody is interested in following validation code changes for a PVF
of a parachain, they would need to subscribe to those events. I did not
supply the topics for the events, since I am not sure if that's needed
or will be used, but they can be added later if needed.

Looks like it is an artifact of prior code and now it is redundant.

This is only a module structure change: the tests module was promoted to
have its own file.

As was brought up in [here][og], we have some copy&paste comments. I
fixed them and also took liberty of fixing some other places.
Specifically, those that say "module" instead of contemporary "pallet".

Closes #3971

Read the linked issue.

Apart from that, this addresses the concern raised in this [comment] by
just adding a test. I couldn't find a clean way to reconcile a block
number delay with a PVF voting TTL, so I just resorted to rely on the
test. Should be fine for now.

This just renames a member of `HostConfiguration` from
validation_upgrade_frequency to -//-_cooldown.

As was already pointed out in #4460 the existing name is a misnomer, the
member actually represents a minimum time period between upgrades, which
is neatly expressed by a word cooldown.

I've been planning this rename already for some time and the term is
already used in paras module:

* paras: add governance control dispatchables

Adds a couple of functions for governance control for the paras module
in the anticipation of PVF pre-checking enabling.

Specifically, this commit adds a function for pre-registering a PVF that
governance trusts enough. This function will come in handy in case there
is a parachain that does not follow the GoAhead signal. That is, does
not include https://github.com/paritytech/cumulus/pull/517.

This may be not an exhaustive list of the functions that may come in
handy. Any suggestions to add more are welcome.

Setting zero as weight may be a source of problems.

The problem is, a rogue validator can shove a lot of duplicated votes
and thus fill a block with work that may well exceed the weight limit.

As was suggested by Alexander Popiak [here][comment], this commit
checks the consistency of the configuration.

Basically updates the docs for the paras module.

Simply extract hardcoded log target into a const.

* pvf-precheck: Integrate PVF pre-checking into paras module

Closes #4009

This is the most of the runtime-side change needed for #3211.

Here is how it works.

The PVF pre-checking can be triggered either by an upgrade or by
onboarding (i.e. calling `schedule_para_initialize`). The PVF
pre-checking process is identified by the PVF code hash that is being
voted on. If there is already PVF pre-checking process running, then no
new PVF pre-checking process will be started. Instead, we just subscribe
to the existing one.

If there is no PVF pre-checking process running but the PVF code hash
was already saved in the storage, that necessarily means (I invite the
reviewers to double-check this invariant) that the PVF already passed
pre-checking. This is equivalent to instant approving of the PVF.

The pre-checking process can be concluded either by obtaining a
supermajority or if it expires.

Each validator checks the list of PVFs available for voting. The vote is
binary, i.e. accept or reject a given PVF. As soon as the supermajority
of votes are collected for one of the sides of the vote, the voting is
concluded in that direction and the effects of the voting are enacted.

Only validators from the active set can participate in the vote. The set
of active validators can change each session. That's why we reset the
votes each session. A voting that observed a certain number of sessions
will be rejected.

The effects of the PVF accepting depend on the operations requested it:

1. All onboardings subscribed to the approved PVF pre-checking process will
get scheduled and after passing 2 session boundaries they will be onboarded.
2. All upgrades subscribed to the approved PVF pre-checking process will
get scheduled very similarly to the existing process. Upgrades with
pre-checking are really the same process that is just delayed by the
time required for pre-checking voting. In case of instant approval the
mechanism is exactly the same. This is important from parachains
compatibility standpoint since following the delayed upgrade requires
the parachain to implement
https://github.com/paritytech/cumulus/pull/517.

In case, PVF pre-checking process was concluded with rejection, then all
the requesting operations get cancelled. For onboarding it means it gets
without movement: the lifecycle of such parachain is terminated on the
`Onboarding` state and after rejection the lifecycle is none. That in
turn means that the caller can attempt registering the parachain once
more. For upgrading it means that the upgrade process is aborted: that
flashes go-ahead signal with `Abort` flag.

Rejection leads to removing the allegedly bad validation code from the
chain storage. Among other things, this implies that the operation can
be re-requested. That allows for retrying an operation in case there was
some bug. At the same time it does not look as a DoS vector due to the
caching performed by the nodes.

PVF pre-checking can be enabled and disabled. Initially, according to
the changes in #4420, this mechanism is disabled. Triggering the PVF
pre-checking when it is disabled just means that we insta approve the
requesting operation. This should lead to the behavior being unchanged.

Follow-ups:

- expose runtime APIs

This PR is a part of
https://github.com/paritytech/polkadot/issues/3211.

This PR prepares ground for the following runtime changes required for
PVF pre-checking. Specifically, we do several changes here:

1. We remove `validation_code_at` and `validation_code_hash_at`. Those
   functions are not used. They were added in the early days with intent
   to use it later but turned out that we do not need them.
2. We replace `validation_code_hash_at` with just `current_code_hash`
   for the case of inclusion and candidate checking.
3. We also replace `last_code_upgrade` with a direct query into
   `FutureCodeHash` and `UpgradeRestrictionSignal`. Those in conjunction
   should replace the logic that was used for allowing/disallowing
   upgrades. This requires special attention of the reviewers.
4. Then we remove the machinery required to support those queries.
   Specifically the code related to `UseCodeAt`. We do not need it since
   we do not answer the historical queries. However, we still leave all
   the data on-chain. At some point we may clean it up, but that would
   be needed to be done with a dedicated migration which can be done as
   follow-up.
5. Some now irrelevant tests were removed and/or adapted.

* rococo-runtime: Switch to latest `construct_runtime!` syntax

Besides that it fixes pallet macro errors in other crates that popped up
because of this switch.

* FMT

* Impose new restrictions on paras init and cleanup

For upcoming PVF pre-checking feature we will need to impose a couple of
new restrictions for:

- `schedule_para_initialize`.
- `schedule_para_cleanup`.

Specifically, for the former we do not want to allow registration of
wasm blob that is empty, i.e. 0 bytes. While that currently already
does not make a lot of sense, it allows us to simplify the PVF
pre-checking logic: if this PR is deployed before the following changes
for PVF prechecking then we can be sure that no paras onboarding have to
have to go through the PVF pre-checking. In case, we deploy it
altogether this property will allow us to distingush paras that came in
before PVF pre-checking.

For `schedule_para_cleanup` we do not want to allow offboarding of paras
that are undergoing the upgrade process. While this is not a harsh
restriction this change allows us to avoid making the PVF prechecking
more complicated than it has to be.

* Add a test for schedule_para_initialize

* Link to `ParaLifecycle::is_stable` in docs.

* `schedule_para_{init,cleanup}` docs

Now they link to their original declarations in the pallet for more
details.

* move things around, add filter methods

* validator keys, modify availability bitfields according to disputes

* simplify, keep the filter -> sanitize generic for both usecases

* assure tests still work, reduce changeset
