vulkan/wsi: Implement GetPhysicalDevicePresentRectanglesKHR
This got missed during 1.1 enabling because it was defined as an interaction between device groups and WSI and it wasn't obvious it was in the delta. The idea behind it is that it's supposed to provide a hint to the application in a multi-GPU setup to indicate which regions of the screen are being scanned out by which GPU so a multi-device split-screen rendering application can render each part of the screen on the GPU that will be presenting it and avoid extra bus traffic between GPUs. On a single-GPU setup or one which doesn't support this present mode, we need to do something. We choose to return the window size (or a max-size rect) if the compositor, X server, or crtc is associated with the given physical device and zero rectangles otherwise.
