Better fix for duplicate wxContextMenuEvent generation under MSW.

Browse Source 
Fix the bug with multiple wxContextMenuEvent being generated for a single
WM_CONTEXTMENU without breaking context menus for wxTextCtrl (and all the
other native controls). Do this by ensuring that WM_CONTEXTMENU is still
passed to DefWindowProc() if we don't process it instead of just being eaten
completely in any case.

Also add a unit test checking for this bug to ensure it stays fixed.

See #13683.
