crypto/keccak: vendor in golang.org/x/crypto/sha3 (#33323) 
The upstream libray has removed the assembly-based implementation of
keccak. We need to maintain our own library to avoid a peformance
regression.

README.md

This is a vendored and modified copy of golang.org/x/crypto/sha3, with an assembly implementation of keccak256. We wish to retain the assembly implementation, which was removed in v0.44.0.

Ethereum uses a 'legacy' variant of Keccak, which was defined before it became SHA3. As such, we cannot use the standard library crypto/sha3 package.
