wl_drm is a legacy interface superseded by the linux-dmabuf
protocol. All clients should migrate.
As a first step, stop creating the wl_drm global by default.
This should let us discover any remaining issues in clients.
Compositors can still manually create the global if they want to.
As a second step, we can completely drop our implementation.
wlr_output.refresh is populated by core wlr_output, and thus will
be zero for a custom mode with an unset refresh rate.
Save the refresh rate from the drmModeModeInfo in wlr_drm_connector
instead.

A lot of protocols extend the wl_surface state. Such protocols need
to synchronize their extended state with wl_surface.commit and
cached states. Add a new utility for this purpose.
`gcc-14` added a new `-Wcalloc-transposed-args` warning recently. It
detected minor infelicity in `calloc()` API usage in `wlroots`:
../backend/libinput/tablet_pad.c: In function 'add_pad_group_from_libinput':
../backend/libinput/tablet_pad.c:36:38: error: 'calloc' sizes specified with 'sizeof' in the earlier argument and not in the later argument [-Werror=calloc-transposed-args]
36 | group->rings = calloc(sizeof(unsigned int), group->ring_count);
| ^~~~~~~~
../backend/libinput/tablet_pad.c:36:38: note: earlier argument should specify number of elements, later size of each element
Before we were populating wlr_output.current_mode with a generated
fixed mode when a custom mode was committed in the DRM backend. But
that's no longer the case: now a custom mode behaves the same under
the DRM backend and other backends.
wlr_output_layout was still assuming that an output without a
current_mode was disabled. Fix that assumption.

We have current and pending state and the code uses struct
assignments between them and resets and frees in multiple places.
Introduce a reset() function so we can unify that.
It can be useful for compositors to get the real DRM FD instead of
the one from the parent compositor. For instance, some compositors
might want to perform some DRM IOCTLs there to check the driver
name, fetch some DRM resources, etc. This will also be a requirement
for direct scanout on secondary GPUs.
