VK_FORMAT_G8B8G8R8_422_UNORM and VK_FORMAT_B8G8R8G8_422_UNORM already place the luminance channel in the green component which is where we NIR lowering code for ycbcr expects it. Set an RGBA swizzle in the common format table and make it the driver's responsibility to re-map the formats as needed for their hardware. The only Vulkan drivers affected by this change are the Intel drivers and lavapipe. None of NVK, RADV, and v3dv support these formats yet and Turnip has its own lowering that doesn't rely on the YCbCr format table in util/vk_format.c.
