Implement support for VK_EXT_image_compression_control_swapchain for both the Wayland and the headless windowing systems. The extension can be conditionally enabled through the new build option BUILD_WSI_IMAGE_COMPRESSION_CONTROL_SWAPCHAIN. Compiling with this option enabled requires recent Vulkan headers (1.3.213) Note also that support in the layer is enabled conditionally to the ICD supporting VK_EXT_image_compression_control. Update the WSIALLOC interface to version 2 and add support to prefer selection of a format with the highest fixed rate compression from the formats provided. This is used to pick a fixed rate compression when VK_IMAGE_COMPRESSION_FIXED_RATE_EXPLICIT_EXT is specified during swapchain creation.
