Filip Gruszczyński 6c5a819a5e reflect: add MakeMapWithSize for creating maps with size hint
Providing size hint when creating a map allows avoiding re-allocating
underlying data structure if we know how many elements are going to
be inserted. This can be used for example during decoding maps in
gob.

Fixes #19599
