With this patch forward this will be the only way for
a contract to destroy itself. This patch therefore changes
the semantics of all other contract initiated balance
transfers to fail if they would bring the caller below the
existential deposit.

* Move runtime upgrade to `frame-executive`

Instead of storing the runtime upgraded in the space of `frame-system`,
this moves it to `frame-executive`. We also start storing the
`spec_version` and `impl_version` the last runtime upgrade was applied.

This scheme has multiple advantages:
- We don't need to make sure that runtime upgrade was set.
- This will work in the future when we want to test a runtime upgrade,
because the `on_runtime_upgrade` will be executed automatically when the
runtime changes.

* Move `LAST_RUNTIME_UPGRADE` key to `frame-executive`

* Add some more documentation

* Make sure `spec_version` always increases between runtime upgrades

* Fix test

* Upgrade `parity-multiaddr` to fix compilation

* Also check if the `spec_name` changed

* Remove `RuntimeUpgraded` storage entry

* Don't run on genesis

* Create release-tagging github action

Uses an action that I forked, which I retain control of for now. Can probably move it to the paritytech repo at some point

* Remove 'prereleased' trigger

`published` action is triggered whether the release is a pre-release or not.

* Update release-tagging.yml

* Remove superfluous cmment

* client/finality-grandpa: Add Prometheus metrics to GossipValidator

Instrument finality grandpa `GossipValidator` exposing count of messages
validated by message type and message action.

```
\# HELP substrate_finality_grandpa_communication_gossip_validator_messages Number of messages validated by the finality grandpa gossip validator.
\# TYPE substrate_finality_grandpa_communication_gossip_validator_messages counter
substrate_finality_grandpa_communication_gossip_validator_messages{action="discard",message="neighbor"} 39
substrate_finality_grandpa_communication_gossip_validator_messages{action="keep",message="vote"} 28
```

* client/finality-grandpa: Add None as Prometheus registry in tests

* client/finality-granpda/src/communication: Refactor metric registration

* contracts: Add ext_transfer call

This call allows contracts to send balance to any account
contract or not. Previously, the only way to do that was
though ext_call.

Up to now `wasm-builder` iterated over all packages that were not part
of the wasm workspace and added the files to the `rerun-if-changed`
list. However, this included to many files and resulted in needless
re-compilations in `Cumulus` for example.

* client/service/src/builder.rs: Add build_info metric

Add static Prometheus metric exposing the chain name, the version and
the commit.

* client/service/src/builder.rs: Move node_role to static metrics

The Prometheus metrics `node_role` is static and thus there is no need
to keep a reference of it within `ServiceMetrics`. This follows the
example of the `build_info` metric.

* client/service/src/builder.rs: Adjust indentation
