Enables compression for select images. Additionally, we get large (64K), and huge (2M) pages as a bonus as the hardware can only do compression on these page sizes. However, due to nouveau limitations, this means that we are limited to enabling it on things pinned to VRAM. Fortunately, this works out for us as we can enable it for color, Z/S, and storage images, which are the main types to benefit from compression as they're write heavy. Unfortunately, this means that we need to handle the memory allocation in a delicate way, as the Vulkan API is a bit restrictive in this regard, so we have to use dedicated allocations for compression/larger pages.
