GStreamer pipeline supports passing multiple colorimetry as a comma
separated list.

For Example :

gst-launch-1.0 libcamerasrc ! "video/x-raw,colorimetry={bt2020,bt709,sRGB}" ! glimagesink

In this case, if supported by the camera one of bt2020, bt709, sRGB
should be applied.

This series aims to adds multiple colorimetry support to the libcamera
gstreamer element.

...
Based on top of [v3 PATCH 4/4] gstreamer: Provide colorimetry <> ColorSpace mappings.

changes from v1 to v2:
- Moved the function colorspace_from_colorimetry() from PATCH 1/2 to
  PATCH 2/2.

changes from v2 to v3:
- Rebase on top of [v3 PATCH 4/4] gstreamer: Provide colorimetry <> ColorSpace mappings.
- Use the comparator utility function gst_video_colorimetry_is_equal()
  to cut down code.
- Rename dup_stream_cfg to pristine_stream_cfg.
- Log the colorimetry that is selected from the list.
- Change the API for the function gst_libcamera_configure_stream_from_caps()
  to pass pass state->config_ here instead of taking it in a holder 
  variable reference.
