video: Add new APIs for HDR information representation
Introduce HDR signalling methods * GstVideoMasteringDisplayInfo: Representing display color volume info. Defined by SMPTE ST 2086 * GstVideoContentLightLevel: Representing content light level specified in CEA-861.3, Appendix A. Closes https://gitlab.freedesktop.org/gstreamer/gst-plugins-base/issues/400
