This notably follow the way we order the template and keeps the format:Interlaced caps at the end. This change also fixes an early skip check, that would skip if a driver only supports alternate interlacing for a specific format. It also fixes a bug where only the last resolution of a discrete frame size was allowed to use format:Interlaced. Finally, similar to template caps code, simplify the caps for earch featurs, making the debug output manageable and (marginally) improve negotiation speed. This change will make it easier to introduce memory:DMABuf. Part-of: <https://gitlab.freedesktop.org/gstreamer/gstreamer/-/merge_requests/7540> |

v4l2 plugins
============
The idea is a bit the same as the idea for the v4l1 plugins. We want
one generic v4l2element, and a few child objects (probably only two:
v4l2src and v4l2sink):
/-------- v4l2src
v4l2element ---=
\-------- v4l2sink
Both v4l2src and v4l2sink have a uncompressed and a compressed
recording-/playback-mode. Since this is all part of v4l2, the 'client'
of these elements, i.e. an application using v4l2src/v4l2sink, will
hardly notice this. All capsnego stuff is done inside, and the plugin
knows which formats are compressed and which are not.
Please note that the v4l1 and the v4l2 plugins are *not* compatible
concerning properties. Naming has been kept the same where possible,
but in some cases, properties had to be removed or added to make
full use of v4l2.
