Roland Shoemaker 4158ca8d7c crypto: add a test for disallowed instructions
WORD and BYTE usage in crypto assembly cores is an anti-pattern which
makes extremely sensitive code significantly harder to understand, and
can result in unexpected behavior.

Because of this, we've decided to ban their usage in the crypto/ tree
(as part of the cryptography assembly policy).

This test walks the crypto/ tree looking for assembly files (those with
the filetype .s) and look for lines that match the regular rexpression
"(^|;)\s(BYTE|WORD)\s".

Roland Shoemaker 509c11f3a3 crypto,crypto/x509: implement MessageSigner
And use it in crypto/x509. This allows people to implement single-shot
signers which do the hashing themselves.

Fixes #63405
