We prior required they had the same encoding, yet this ensures they do by
making them one and the same. This does require an large, ugly, From/TryInto
block which is deemed preferable for moving this more and more into syntax
(from semantics).
Further improvements (notably re: Extra) is possible, and this already lets us
strip some members from the Call enum.
* implement general design
* add slashing
* bug fixes
* fix pr comments
* misc fixes
* fix grandpa abi call type
* Correct rebase artifacts I introduced
* Cleanups and corrections
1) Uses vec![] for the OpaqueKeyProof as there's no value to passing it around
2) Remove usage of Babe/Grandpa Offences for tracking if an offence is known
for checking if can slash. If can slash, no prior offence must have been
known.
3) Rename DisabledIndices to SeraiDisabledIndices, drop historical data for
current session only.
4) Doesn't remove from the pre-declared upcoming Serai set upon slash due to
breaking light clients.
5) Into/From instead of AsRef for KeyOwnerProofSystem's generic to ensure
safety of the conversion.
* Correct deduction from TotalAllocatedStake on slash
It should only be done if in set and only with allocations contributing to
TotalAllocatedStake (Allocation + latest session's PendingDeallocation).
* Changes meant for prior commit

Uses a full-fledged serai-abi to do so.
Removes use of UncheckedExtrinsic as a pointlessly (for us) length-prefixed
block with a more complicated signing algorithm than advantageous.
In the future, we should considering consolidating the various primitives
crates. I'm not convinced we benefit from one primitives crate per pallet.
Call and Event are both from the pallets, which are AGPL licensed. Accordingly,
they make serai-client AGPL licensed when serai-client must end up MIT
licensed. This creates a MIT-licensed variant of Calls and Events such that
they can be used by serai-client, enabling transitioning it to MIT.
Relevant to https://github.com/serai-dex/serai/issues/337.
