  [ADT,CodeGen] Remove stable_hash_combine_string

FNV, used by stable_hash_combine_string is extremely slow. For string
hashing with good avalanche effects, we prefer xxh3_64bits.

StableHashing.h might still be useful as it provides a stable
hash_combine while Hashing.h's might be non-deterministic (#96282).
