Obvious code cleanup is obvious.

Move serai-client off serai-runtime, MIT licensing it
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.

Remove subxt (#460)
* Remove subxt

Removes ~20 crates from our Cargo.lock.

Removes downloading the metadata and enables removing the getMetadata RPC route
(relevant to #379).

Moves forward #337.

Done now due to distinctions in the subxt 0.32 API surface which make it
justifiable to not update.

* fmt, update due to deny triggering on a yanked crate

* Correct the handling of substrate_block_notifier now that it's ephemeral, not long-lived

* Correct URL in tests/coordinator from ws to http

Replace bincode with borsh (#452)
* Add SignalsConfig to chain_spec

* Correct multiexp feature flagging for rand_core std

* Remove bincode for borsh

Replaces a non-canonical encoding with a canonical encoding which additionally
should be faster.

Also fixes an issue where we used bincode in transcripts where it cannot be
trusted.

This ended up fixing a myriad of other bugs observed, unfortunately.
Accordingly, it either has to be merged or the bug fixes from it must be ported
to a new PR.

* Make serde optional, minimize usage

* Make borsh an optional dependency of substrate/ crates

* Remove unused dependencies

* Use [u8; 64] where possible in the processor messages

* Correct borsh feature flagging

Various simplifications re: Serai transactions
Removes PairSigner for the pair directly.

Resets spec_version to 1.

Defines the extrinsic without its length prefix, only prefixing during publish.

dockertest 0.4 (#406)
* Updates to modern dockertest

* More updates to latest dockertest

* Update Cargo.lock to dockertest with handle restored

* clippy coordinator tests

* clippy full-stack tests

* Remove kayabaNerve branch for official repo's latest commit hash

* Update serai-client, remove reliance on the existence of a handle fn

* Don't use the hex encoding of unique_id in dockertests

Gets our hostnames just below 64 bytes, resolving test failures on at least
Debian-based systems.

* Use Network::Isolated for all dockertest instances

* Correct error from prior commit's edits

Resolve #327
Also runs `cargo update` and moves where we install the wasm toolchain in the
Dockerfile for better caching properties.

cb61c9052a Reorganize serai-client
Instead of functions taking a block hash, has a scope to a block hash before
functions can be called.

Separates functions by pallets.

Alternate handover batch TOCTOU fix (#397)
* Revert "Correct the prior documented TOCTOU"

This reverts commit d50fe87801.

* Correct the prior documented TOCTOU

d50fe87801 edited the challenge for the Batch to
fix it. This won't produce Batch n+1 until Batch n is successfully published
and verified. It's an alternative strategy able to be reviewed, with a much
smaller impact to scope.

Correct the prior documented TOCTOU
Now, if a malicious validator set publishes a malicious `Batch` at the last
moment, it'll cause all future `Batch`s signed by the next validator set to
require a bool being set (yet they never will set it).

This will prevent the handover.

The only overhead is having two distinct `batch_message` calls on-chain.

Staking pallet (#373)
* initial staking pallet

* add staking pallet to runtime

* support session rotation for serai

* optimizations & cleaning

* fix deny

* add serai network to initial networks

* a few tweaks & comments

* fix some pr comments

* Rewrite validator-sets with logarithmic algorithms

Uses the fact the underlying DB is sorted to achieve sorting of potential
validators by stake.

Removes release of deallocated stake for now.

Add Batch messages from processor, verify Batchs published on-chain
Renames Update to SignedBatch.

Checks Batch equality via a hash of the InInstructions. That prevents needing
to keep the Batch in node state or TX introspect.

Use proper messages for ValidatorSets/InInstructions pallet
Provides a DST, and associated metadata as beneficial.

Also utilizes MuSig's context to session-bind. Since set_keys_messages also
binds to set, this is semi-redundant, yet that's appreciated.
