This little series adds support for enabling CCS_E for images which may have VK_IMAGE_USAGE_STORAGE_BIT set. Previously, we just bailed on these images and disabled CCS. However, so long as we do a full resolve when entering VK_IMAGE_LAYOUT_GENERAL, we can support CCS_E for all the other layouts just fine.
The primary motivation of this series is actually by trying to get better test coverage of our resolve code. By doing resolves when going into VK_IMAGE_LAYOUT_GENERAL, the full resolve paths now get tested on many more image types. I have no idea what the perf impact of this will be. The first 4 patches just make use use layout_to_* more often.
