drm_atomic: Add general primary/overlay plane option

Browse Source 
Add general primary/overlay plane option to drm-osd-plane-id and
drm-video-plane-id, so that the user can just request any usable
primary or overlay plane for either of these two options. This should
be somewhat more user-friendly (especially as neither of these two
options currently have a useful help function), as usually you would
only be interested in the type of the plane, and not exactly which
plane gets picked.

--- mpv 0.30.0 ---
- the `--drm-osd-plane-id` and `--drm-video-plane-id`
options now accept either an integer index, or the values primary or overlay.
`--drm-osd-plane-id` now defaults to primary and `--drm-video-plane-id`
defaults to overlay. This should be similar to previous behavior on most drivers
due to how planes are usually sorted.
- rename --opensles-frames-per-buffer to --opensles-frames-per-enqueue to
better reflect its purpose. In the past it overrides the buffer size the AO
requests (but not the default/value of the generic --audio-buffer option).

Mode ID to use (resolution and frame rate).
(default: 0)
``--drm-osd-plane-id=<number>``
Select the DRM plane index to use for OSD (or OSD and video).
Index is zero based, and related to crtc.
When using this option with the drm_prime renderer, it will only affect
the OSD contents. Otherwise it will set OSD & video plane.
(default: primary plane)
``--drm-osd-plane-id=<primary|overlay|N>``
Select the DRM plane to use for OSD (or OSD and video). The plane can be
specified as ``primary``, which will pick the first applicable primary
plane; ``overlay``, which will pick the first applicable overlay plane;
or by index. The index is zero based, and related to the CRTC. When using
this option with the drm_prime renderer, it will only affect the OSD
contents. Otherwise it will set OSD & video plane.
(default: primary)
``--drm-video-plane-id=<number>``
Select the DRM plane index to use for video layer.
Index is zero based, and related to crtc.
This option only has effect when using the drm_prime renderer (which
supports several layers) together with ``vo=gpu`` and ``gpu-context=drm``.
(default: first overlay plane)
``--drm-video-plane-id=<primary|overlay|N>``
Select the DRM plane index to use for video layer. This option accepts
the same values as ``--drm-osd-plane-id``. This option has an effect
only when using the drm_prime renderer (which supports several layers)
together with ``vo=gpu`` and ``gpu-context=drm``.
(default: overlay)
``--drm-format=<xrgb8888|xrgb2101010>``
Select the DRM format to use (default: xrgb8888). This allows you to
