wayland: port to the new wakeup/wait_events framework

This fits natively into the vo/backend and allows to simplify the
polling code.
One new change is the fact that surface_handle_enter flags VO_EVENT_WIN_STATE
and VO_EVENT_RESIZE instead of only VO_EVENT_WIN_STATE. Before this, the code
hackily relied on the timeout and the loop in the wait_frame function to track
and set the scaling factor. Instead, this triggers mpv to run a schedule_resize
and adjust the new VO output dimensions immediately. This is also more accurate
since surface_handle_enter() gets called when a surface is created, moved and
resized, which is exactly what the rest of the player might be interested in.
