The problem with this is that TLB clears always clear and store full
tiles, so if our render area is not perfectly aligned to tile boundaries
we end up clearing all pixels in tiles that are only partially covered.
In this scenario we have to avoid using TLB clears and instead fallback
to clearing by rendering a scissored quad in the clear color, like we do
for partial clears in vkCmdClearAttachments.
