Azat Khuzhin 4366f7fb3b Remove PREALLOCATE for HASHED/SPARSE_HASHED dictionaries
It does not give significant benefit, but now, you hashed/sparse_hashed
dictionaries can be filled in parallel (#40003), using sharded
dictionaries, and this should be used instead of PREALLOCATE.

Note, that dictionaries, that had been created with PREALLOCATE will
work, but simply ignore this attribute.

Fixes: #41985 (cc @alexey-milovidov)
Reverts: #23979 (cc @kitaisreal)
