Simon Ser 7201aae3d6 render/drm-format-set: add wlr_drm_format_set_intersect 
This intersects two DRM format sets. This is useful for implementing
DMA-BUF feedback in compositors, see e.g. the Sway PR [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.
