Convert ShardedHashMap to use hashbrown::HashTable

[cuviper]

The hash_raw_entry feature (#56167) has finished fcp-close, so the compiler
should stop using it to allow its removal. Several Sharded maps were
using raw entries to avoid re-hashing between shard and map lookup, and
we can do that with hashbrown::HashTable instead.

Oh, I see, the import was removed by #138040. I'll rebase and fix it.

PR checks are passing, so we should be good to go!
