Move cryptographic hashing procedures to crypto folder. (#2306)

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
