When a surface is to be created for a buffer that is to be persistently mapped, set the UAV bind flag as well, otherwise, an extra copy of the surface will have to be created when the buffer is later bound as shader storage buffer, and it will then incur extra buffer copies to keep the shadow copies of the surface in sync. But when a buffer is simultanously bound to uniform buffer and shader storage buffer, having both srv and uav on the same resource can also be costly. This patch also provides optimization for readonly shader buffer. In this case, instead of creating uav for accessing a readonly shader buffer, srv raw buffer is used instead. Tested with yuzu tracefile included in VMware bug 3029385. Reviewed-by: Martin Krastev <krastevm@vmware.com> Part-of: <https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/25381>
