Introduces `CryptoBytes` type defined as:
```rust
pub struct CryptoBytes<const N: usize, Tag = ()>(pub [u8; N], PhantomData<fn() -> Tag>);
```
The type implements a bunch of methods and traits which are typically
expected from a byte array newtype
(NOTE: some of the methods and trait implementations IMO are a bit
redundant, but I decided to maintain them all to not change too much
stuff in this PR)
It also introduces two (generic) typical consumers of `CryptoBytes`:
`PublicBytes` and `SignatureBytes`.
```rust
pub struct PublicTag;
pub PublicBytes<const N: usize, CryptoTag> = CryptoBytes<N, (PublicTag, CryptoTag)>;
pub struct SignatureTag;
pub SignatureBytes<const N: usize, CryptoTag> = CryptoBytes<N, (SignatureTag, CryptoTag)>;
```
Both of them use a tag to differentiate the two types at a higher level.
Downstream specializations will further specialize using a dedicated
crypto tag. For example in ECDSA:
```rust
pub struct EcdsaTag;
pub type Public = PublicBytes<PUBLIC_KEY_SERIALIZED_SIZE, EcdsaTag>;
pub type Signature = PublicBytes<PUBLIC_KEY_SERIALIZED_SIZE, EcdsaTag>;
```
Overall we have a cleaner and most importantly **consistent** code for
all the types involved
All these details are opaque to the end user which can use `Public` and
`Signature` for the cryptos as before
This is the significant step to make BEEFY client able to handle both
ECDSA and (ECDSA, BLS) type signature. The idea is having BEEFY Client
generic on crypto types makes migration to new types smoother.
This makes the BEEFY Keystore generic over AuthorityId and extends its
tests to cover the case when the AuthorityId is of type (ECDSA,
BLS12-377)

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

Next step in process of making BEEFY being able to generate both ECDSA
and BLS signature after #1705. It allows BEEFY to use a pair of ECDSA
and BLS key as a AuthorityId.

BEEFY needs two cryptographic keys at the same time. Validators should
sign BEEFY payload using both ECDSA and BLS key. The network will gossip
a payload which contains a valid ECDSA key. The prover nodes aggregate
the BLS keys if aggregation fails to verifies the validator which
provided a valid ECDSA signature but an invalid BLS signature is subject
to slashing.
As such BEEFY session should be initiated with both key. Currently there
is no straight forward way of doing so, beside having a session with
RuntimeApp corresponding to a crypto scheme contains both keys.
This pull request implement a generic paired_crypto scheme as well as
implementing it for (ECDSA, BLS) pair.
