Fix bugs in wxEnumProperty introduced by r76562.

The compilation fixes introduced run-time fixes due to not account for the use
of NULL pointers (which are not accepted as choices cache but are accepted as
choices values, go figure).

Closes #16266.

Don't use the deprecated 'register' storage specifier.

It is not only useless with any modern C++ compiler, but also deprecated
in C++11.  Removing it fixes Clang warnings on the subject.

Don't destroy wxFont from its GetFaceName() in wxMSW.

wxFont::GetFaceName() could destroy the HFONT used by the font accidentally,
avoid it by not invalidating the font when caching its face name.

Closes #16273.

Fix changing individual font properties in the propgrid sample.

Fixes the bug in the sample which resulted in the UI not working as expected.

Closes #12779.

Avoid showing the colour selection dialog twice in wxPropertyGrid.

Selecting "Custom" in a colour property cell resulted in the colour selection
dialog being shown twice if it was cancelled the first time.

Fix this by using wxPG_PROPERTY_SPECIFIC to indicate that the value is just
being queried and the user shouldn't be asked to enter it, as it is already in
the other places.

Closes #15543.

Disable another wxStopWatch test case in the build bot builds.

We can't rely on the program waking up quickly enough when running on the
(loaded) buildbot machines, better to skip this test than to have spurious
failures.

Return wxWinVersion_[78] correctly from wxMSW wxGetWinVersion().

This is especially important because the workaround of r76152 for IFileDialog
bug under Windows Vista also applied under later Windows versions as they were
not detected correctly.
