Print the pixel format chosen for an output on a secondary GPU for debugging. Knowing the format can aid in debugging e.g. red/blue channel swaps and CPU copy performance issues. This adds a DRM format printing helper in meta-crtc-kms.h. This header is included in most native backend files making it widely available, while DRM formats are specific to the native backend. It could be shared with Wayland bits, DRM format codes are used there too. The helper makes the pixel format much more readable than a "%x". https://gitlab.gnome.org/GNOME/mutter/merge_requests/341
