Azat Khuzhin 808d1a0215 Reimplement preallocate for hashed/sparse_hashed dictionaries
It was initially implemented in #15454, but was reverted in #21948 (due
to higher memory usage).

This implementation differs from the initial, since now there is
separate attribute to enable preallocation, before it was done
automatically, but this has problems with duplicates in the source.

Plus this implementation does not uses dynamic_cast, instead it extends
IDictionarySource interface.
