Improve wlr_drm_format documentation
...
A wlroots user can easily get confused and think that `cap` refers to
wlroots buffer capabilities, not array capacity.

render/drm_format_set: remove special LINEAR case
...
This was used to make the intersection of INVALID and LINEAR result
in LINEAR. We can now just require LINEAR to be in both lists.

render/drm_format_set: add special case for LINEAR-only formats
...
Our wlr_format_set structs don't hold GBM usage flags. Instead, users
who want to get a LINEAR buffer can use the DRM_FORMAT_MOD_LINEAR
modifier even if the kernel driver doesn't support modifiers.
Add a special case to wlr_drm_format_intersect to properly handle this
situation.

render/drm_format_set: allocate using cap when duplicating
...
In wlr_drm_format_dup, allocate the new wlr_drm_format using cap instead
of len. This makes it so the cap field is up-to-date and the chunk of
memory isn't too small if we append new modifiers (we don't allow this
yet but might in the future).

render/drm_format_set: introduce wlr_drm_format_intersect
...
Intersects modifiers from two wlr_drm_format structs. If either format
doesn't support modifiers, the resulting format won't support modifiers.

render/drm_format_set: disallow DRM_FORMAT_INVALID
...
It doesn't make sense to add DRM_FORMAT_INVALID to a format set. Adding
an assertion allows us to safely query the format set with
DRM_FORMAT_INVALID. See [1].

render: introduce wlr_drm_format_set
...
This types adds a container for formats + modifiers.
A list that is of [format [modifier]] was chosen instead of
[format modifer] because that is how GBM accepts them.
