Guido Tagliavini Ponce f105e1a501 Make the per-shard hash table fixed-size. (#10154) 
Summary:
We make the size of the per-shard hash table fixed. The base level of the hash table is now preallocated with the required capacity. The user must provide an estimate of the size of the values.

Notice that even though the base level becomes fixed, the chains are still dynamic. Overall, the shard capacity mechanisms haven't changed, so we don't need to test this.

Pull Request resolved: https://github.com/facebook/rocksdb/pull/10154

Test Plan: `make -j24 check`
