Samuel Pitoiset 46e8ba1344 radv: only inject implicit subpass dependencies if necessary
The Vulkan 1.2.134 spec update clarified when implicit subpass
dependencies should be injected by the driver. They only make
sense if automatic layout transitions are performed.

This should fix a performance regression with RPCS3 (although
they added a workaround for RADV since the regression has been found).

Closes: https://gitlab.freedesktop.org/mesa/mesa/issues/2502
Fixes: e60de08547 ("radv: handle missing implicit subpass dependencies")
