  [StableHash] Implement stable global name for the hash computation (#106156)

LLVM often extends global names by adding suffixes to distinguish unique
identities. However, these suffixes are not always stable across
different runs and build environments. To address this issue, I
implemented `get_stable_name` to ignore such suffixes and obtain the
original name. This approach is not new, as PGO or Bolt already handle
this issue similarly. Using the stable name obtained from
`get_stable_name`, I implemented `stable_hash_name` while utilizing the
same underlying `xxh3_64bit` algorithm as before.
