Step towards https://github.com/paritytech/polkadot-sdk/issues/1975

As reported
https://github.com/paritytech/polkadot-sdk/issues/1975#issuecomment-1774534225
I'd like to encapsulate crypto related stuff in a dedicated folder.

Currently all cryptographic primitive wrappers are all sparsed in
`substrate/core` which contains "misc core" stuff.

To simplify the process, as the first step with this PR I propose to
move the cryptographic hashing there.

The `substrate/crypto` folder was already created to contains `ec-utils`
crate.

Notes:
- rename `sp-core-hashing` to `sp-crypto-hashing`
- rename `sp-core-hashing-proc-macro` to `sp-crypto-hashing-proc-macro`
- As the crates name is changed I took the freedom to restart fresh from
version 0.1.0 for both crates

* - Make `BeefyApi` generic over Signature type.
- Make new `BeeyApi` functinos also generic over AuthorityId and Signature

* Unmake BeefyAPI generic over Signature. Recover Signature type from AuthId.

* - dont use hex or hex-literal use array-bytes instead in beefy primitives and bls crypto.
- CamelCase ECDSA and BLS everywhere.

* Move the definition of BEEFY key type from `primitives/beefy` to `crypto.rs` according to new convention.

* - Add bls377_generate_new to `sp-io` and `application_crypto::bls`.
- Add `bls-experimental` to `sp-io`

Does not compile because PassByCodec can not derive PassBy using customly implemented PassByIner.

* Implement PassBy for `bls::Public` manually

* fix Beefy `KEY_TYPE` in `frame/beefy` tests to come from `sp-core::key_types` enum

* Make commitment and witness BEEFY tests not use Keystore.

* put `bls_beefy_verify_works` test under `bls-experimental` flag.

* bump up Runtime `BeefyAPI` to version 3 due to introducing generic AuthorityId.

* client/beefy: don't accept vote for older rounds

* client/beefy: clean up and reorg the worker struct

* client/beefy: first step towards Full BEEFY

The first step from Lean->Full BEEFY is to have the worker
enforce uninterrupted line of BEEFY finalized mandatory blocks.

There is one mandatory block per session (the first block in the
session). As such, votes processing and votes generation now
enforces that all mandatory blocks are finalized in strict
monotonically increasing sequence and no block 'N' will be worked
on if there is any GRANDPA finalized but BEEFY non-final mandatory
block 'M', where 'M < N'.

Implementation details:

- Introduced 'VoterOracle' to separate the voting decisions logic,
  and track new/pending sessions.

- New sessions get queued up with the worker operating either:
  1. up-to-date - all mandatory blocks leading up to current GRANDPA
     finalized: queue has ONE element, the 'current session' where
     `mandatory_done == true`,
  2. lagging behind GRANDPA: queue has [1, N] elements, where all
     `mandatory_done == false`.
     In this state, everytime a session gets its mandatory block
     BEEFY finalized, the session is popped off the queue,
     eventually getting to operating mode `1. up-to-date`.

- Votes get triaged and those that fall withing the `VoterOracle`
  allowed window get processed, the others get dropped if stale,
  or buffered for later processing (when they reach the window).

- Worker general code was also updated to fall in one of two roles:
  1. react to external events and change internal 'state',
  2. generate events/votes based on internal 'state'.
