[client] wayland: harden native HDR colour state

Browse Source 
Serialize asynchronous image-description state and publish compositor
capabilities safely across the Wayland and render threads.

Use the predefined Windows-scRGB description, query each output image
description for its configured reference white, and reapply HDR when the
surface moves to an output with different colour settings.
