radv: Use VK_IMAGE_LAYOUT_ATTACHMENT_FEEDBACK_LOOP_OPTIMAL_EXT for render loops

This commit fixes
dEQP-VK.rasterization.rasterization_order_attachment_access.format on
GFX9 because changing the layout for Vulkan feedback loops will trigger
a fast-clear eliminate.  Though, the root cause is unrelated to that and
it's because the CMASK/FMASK initialization on GFX9 is currently broken
for TC-compatible images (there is a TODO somewhere).
