Process pending events from wxYield() in wxGTK.

Calling wxYield() is supposed to process the pending events but it didn't, any
more, in wxGTK. Restore this by explicitly calling ProcessPendingEvents() from
wxGTK wxYield() implementation as wxGUIEventLoop::ProcessIdle() does not call
it, in spite of a comment to the contrary in the sources.

Closes #14760.
