winewayland.drv: Make access to Wayland output information thread-safe.

Browse source 
Store all incoming Wayland output state as pending and make it current
in a thread-safe way when the "done" event arrives. This enables other
threads, with proper locking, to safely read consistent and complete
Wayland output information.
