This PR implements the base fee syscall API method. Currently this is
implemented as a compile time constant in the revive compiler, returning
0. However, since this is an opocde, if we ever need to implement it for
compatibility reasons with
[EIP-1559](https://github.com/ethereum/EIPs/blob/master/EIPS/eip-1559.md),
it would break already deployed contracts. Thus we provide a syscall
method instead.

This PR implements the EVM gas price syscall API method. Currently this
is a compile time constant in revive, but in the EVM it is an opcode.
Thus we should provide an opcode for this in the pallet.

- Fixed failing docs.rs build for `pallet-revive-uapi` by fixing a wring
attribute in the manifest (we were using `default-target` instead of
`targets`)
- Removed the macros defining host functions because the cfg attributes
introduced in #6866 won't work on them
- Added an docs.rs specific attribute so that the `unstable-hostfn`
feature tag will show up on the functions that are guarded behind it.

#6940

Call data, return data and code sizes can never exceed `u32::MAX`; they
are also not generic. Hence we know that they are guaranteed to always
fit into a 64bit register and `revive` can just zero extend them into a
256bit integer value. Which is slightly more efficient than passing them
on the stack.

#6450 introduced metadata checks. Supported are metadata v14 and higher.

However, of course old chain-specs have a genesis code blob that might
be on older version. This needs to be tolerated. We should just skip the
checks in that case.

# Description

Fixes https://github.com/paritytech/polkadot-sdk/issues/5996

https://github.com/libp2p/rust-libp2p/releases/tag/libp2p-v0.53.0
https://github.com/libp2p/rust-libp2p/blob/master/CHANGELOG.md

## Integration

Nothing special is needed, just note that `yamux_window_size` is no
longer applicable to libp2p (litep2p seems to still have it though).

## Review Notes

There are a few simplifications and improvements done in libp2p 0.53
regarding swarm interface, I'll list a few key/applicable here.

https://github.com/libp2p/rust-libp2p/pull/4788 removed
`write_length_prefixed` function, so I inlined its code instead.

https://github.com/libp2p/rust-libp2p/pull/4120 introduced new
`libp2p::SwarmBuilder` instead of now deprecated
`libp2p::swarm::SwarmBuilder`, the transition is straightforward and
quite ergonomic (can be seen in tests).

https://github.com/libp2p/rust-libp2p/pull/4581 is the most annoying
change I have seen that basically makes many enums `#[non_exhaustive]`.
I mapped some, but those that couldn't be mapped I dealt with by
printing log messages once they are hit (the best solution I could come
up with, at least with stable Rust).

https://github.com/libp2p/rust-libp2p/issues/4306 makes connection close
as soon as there are no handler using it, so I had to replace
`KeepAlive::Until` with an explicit future that flips internal boolean
after timeout, achieving the old behavior, though it should ideally be
removed completely at some point.

`yamux_window_size` is no longer used by libp2p thanks to
https://github.com/libp2p/rust-libp2p/pull/4970 and generally Yamux
should have a higher performance now.

I have resolved and cleaned up all deprecations related to libp2p except
`BandwidthSinks`. Libp2p deprecated it (though it is still present in
0.54.1, which is why I didn't handle it just yet). Ideally Substrate
would finally [switch to the official Prometheus
client](https://github.com/paritytech/substrate/issues/12699), in which
case we'd get metrics for free. Otherwise a bit of code will need to be
copy-pasted to maintain current behavior with `BandwidthSinks` gone,
which I left a TODO about.

The biggest change in 0.54.0 is
https://github.com/libp2p/rust-libp2p/pull/4568 that changed transport
APIs and enabled unconditional potential port reuse, which can lead to
very confusing errors if running two Substrate nodes on the same machine
without changing listening port explicitly.

Overall nothing scary here, but testing is always appreciated.

The timeout was too low which made the job not finish in time sometimes:

Hence:
- Bumping the timeout to 60 minutes which is in line with other jobs
which are building substantial parts of the repo.
- Roll all the runtime builds into a single cargo invocation so that it
aborts after the first failure. It also allows for more parallel
compiling.

Bump `polkavm` to 0.18.0, and update `sc-polkavm-executor` to be
compatible with the API changes. In addition, bump also `polkavm-derive`
and `polkavm-linker` in order to make sure that the all parts of the
Polkadot SDK use the exact same ABI for `.polkavm` binaries.

Purely relying on RV32E/RV64E ABI is not possible, as PolkaVM uses a
RISCV-V alike ISA, which is derived from RV32E/RV64E but it is still its
own microarchitecture, i.e. not fully binary compatible.

Approval voting canonicalize is off by one that means if we are
finalizing blocks one by one, approval-voting cleans it up every other
block for example:

- With 1, 2, 3, 4, 5, 6 blocks created, the stored range would be
StoredBlockRange(1,7)
- When block 3 is finalized the canonicalize works and StoredBlockRange
is (4,7)
- When block 4 is finalized the canonicalize exists early because of the
`if range.0 > canon_number` break clause, so blocks are not cleaned up.
- When block 5 is finalized the canonicalize works and StoredBlockRange
becomes (6,7) and both block 4 and 5 are cleaned up.

The consequences of this is that sometimes we keep block entries around
after they are finalized, so at restart we consider this blocks and send
them to approval-distribution.

In most cases this is not a problem, but in the case when finality is
lagging on restart approval-distribution will receive 4 as being the
oldest block it needs to work on, and since BlockFinalized is never
resent for block 4 after restart it won't get the opportunity to clean
that up. Therefore it will end running approval-distribution aggression
on block 4, because that is the oldest block it received from
approval-voting for which it did not see a BlockFinalized signal.

The `SlotBasedBlockImport` job is to collect the storage proofs of all
blocks getting imported. These storage proofs alongside the block are
being forwarded to the collation task. Right now they are just being
thrown away. More logic will follow later. Basically this will be
required to include multiple blocks into one `PoV` which will then be
done by the collation task.
