Simon Ser 6d281d96cb 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.

Simon Ser ea7357b703 Require INVALID for implicit format modifiers
See [1] for the motivation.

Simon Ser c4635c68d2 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).

Simon Ser 82443ea46b 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.

Simon Ser 01d4506253 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.
