Restore generic GetPartialTextExtents() version use in wxGTK and wxMSW.

Non-wxWindowDC-derived wxDC classes in wxGTK, such as wxGtkPrinterDCImpl, have
to fall back on the generic implementation of GetPartialTextExtents() as Pango
version can't be used with them.

This fixes a crash due to using NULL Pango layout when printing wxRichTextCtrl
in wxGTK.

Closes #14847.

Fix TAB navigation in wxGTK broken by r72663.

Don't call SetCanFocus(true) for container windows with focusable children,
this doesn't play well at all with wxGTK focus handling and in particular
totally disabled TAB navigation.

Fix wxGenericListCtrl scrolling by not processing the events twice.

Scrolling wxGenericListCtrl was broken since r72939 because its OnScroll()
event handler explicitly called wxScrollHelper::HandleOnScroll() which was
also called by the base class ProcessEvent().

Arguably, wxScrollHelper::ProcessEvent() should be updated to allow handling
events directly like this by not processing it again if the event wasn't
skipped but for now just do skip the event and let the default handling take
place which at least makes wxGenericListCtrl work correctly again.

Closes #14852.

It was already disabled for VC6 but VC7 doesn't compile this code neither, so
