Previously we had many different code paths all
handling digests in different places, all with
wildly different digest support. This commit
rewrites this to use a single digest handling
mechanism for all digest operations.
It adds various aliases for digest algorithms,
like node does. For example
`sha1WithRSAEncryption` is an alias for `sha1`.
It also adds support for `md5-sha1` digests in
various places.
Changes in this PR:
- Added new fixed size hash algorithms (blake2b512, blake2s256,
sha512-224, sha512-256, sha3-224, sha3-256, sha3-384, sha3-512, sm3)
- Added variable size hash algorithms (the concept), with the algorithms
shake128 and shake256
- Use cppgc instead of resources for the hasher
- Enable Node's crypto.Hash tests and fix found bugs
