Subject: Tune compilation flags to reduce libraries size

Add '_WINDLL' definition for the MSVC compilers family.
Check the 'FEATURE_optimize_size' value before replacing compiler flags
in the qt_internal_add_optimize_full_flags function. This is required,
because Qt::Core and Qt::Gui modules lost their ability to shrink,
when selecting the appropriate build type or features.

Fixes: QTBUG-89952
