Wayland: Fix heuristics for what counts as events

Browse Source 
The Wayland implementation of glfwWaitEvents* keeps waiting until it
sees evidence that a significant event has been processed.  However,
this included updating an animated cursor (not a significant event)
but did not include previously buffered Wayland events or libdecor
events (definitely significant events).

This commit corrects these cases.
