Russ Cox 57d05512fe crypto/subtle: add XORBytes
Export cipher.xorBytes as subtle.XORBytes, for proposal #53021,
to provide fast XOR to cryptography libraries outside crypto/cipher.

Along with the move, implement the alignment check TODO
in xor_generic.go, so that systems with neither unaligned
accesses nor custom assembly can still XOR a word at a time
in word-based algorithms like GCM. This removes the need
for the separate cipher.xorWords.

Fixes #53021.
