player: remove all rpi-specific code

vo_rpi and its related code has pretty much historically been a
disaster in mpv. The build regularly gets broken and since nobody uses
it, it takes months for anyone to notice. There was also that time where
fullscreen was broken for about a year and a half. Also building in waf
was entirely broken for about a couple of years or so due to mysterious
reasons no one ever figured out (meson magically fixed it).

Anyways, once again the build is broken due to rpi being forgotten about
again, but instead of pretending to support this crap. Just drop it all.
Nowadays, mmal hwdec is a relic since these devices are better off using
the v4l2m2m ffmpeg fork instead which actually uses KMS properly. RPI 1
and 2 probably can't do this and will remain broken but oh well blame
Broadcom for being special snowflakes and not using standard APIs (my
rockpro worked out of the box; just saying). RPI 2 is nearly 10 years
old anyways, so I think you can afford a new SBC by now. If we were
nicer, there would be a deprecation period, but this is broken in the
last major release anyway so too late.

Closes #13402.

     This also supports many of the options the ``gpu`` VO has, depending on the
     backend.
 
-``rpi`` (Raspberry Pi)
-    Native video output on the Raspberry Pi using the MMAL API.
-
-    The following global options are supported by this video output:
-
-    ``--rpi-display=<number>``
-        Select the display number on which the video overlay should be shown
-        (default: 0).
-
-    ``--rpi-layer=<number>``
-        Select the dispmanx layer on which the video overlay should be shown
-        (default: -10). Note that mpv will also use the 2 layers above the
-        selected layer, to handle the window background and OSD. Actual video
-        rendering will happen on the layer above the selected layer.
-
-    ``--rpi-background=<yes|no>``
-        Whether to render a black background behind the video (default: no).
-        Normally it's better to kill the console framebuffer instead, which
-        gives better performance.
-
-    ``--rpi-osd=<yes|no>``
-        Enabled by default. If disabled with ``no``, no OSD layer is created.
-        This also means there will be no subtitles rendered.
