Stenzek de632fc9c8 Renderer: Handle resize events on-demand instead of polling
We now differentiate between a resize event and surface change/destroyed
event, reducing the overhead for resizes in the Vulkan backend. It is
also now now safe to change the surface multiple times if the video thread
is lagging behind.
