anv: Handle color layout transitions from the UNINITIALIZED layout

This causes dEQP-VK.api.copy_and_blit.resolve_image.partial.* to start
failing due to test bugs.  See CL 1031 for a test fix.

+    * This comment is a bit cryptic and doesn't really tell you what's going

+    * properly synchronized with other drawing.  This means that we cannot
+    * have a fast clear operation in the pipe at the same time as other
+    * regular drawing operations.  We need to use a PIPE_CONTROL to ensure
+    * that the contents of the previous draw hit the render target before we
+    * resolve and then use a second PIPE_CONTROL after the resolve to ensure
+    * that it is completed before any additional drawing occurs.
