lavapipe: Block YCbCr formats from getting blit feature flags
What does this MR do and why?
I missed this when adding new RGB pipe_formats for the 10 and 12-bit VK_FORMATs.
Block all YCbCr formats from getting blit feature flags by using vk_format_ycbcr_info, which will make it less error-prone in the future.
