Nikolay Sivov df65aee926 comctl32: Switch back to internal allocation function. 
We are still using exported string functions internally,
and that caused mismatches after recent incomplete switching to crt functions.

There is also no evidence that crt functions are used at all there,
so for now switch back to fix mismatching calls.
