All of the issues that this patch fixes should not occur in practice,
but make the code a bit more robust. For example, this patch
default-initializes structures passed to Vulkan for initialization.
Normally, initialization should be done by the Vulkan entrypoint,
so it should be fine not initializing the structure as long as the
Vulkan API entrypoint exits with success status. It is still a good
idea to default-initialize anyway to make the behaviour deterministic
in cases where something is wrong in the system. All changes made
should have a negligible impact on performance for typical
applications.

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.
