Vignesh Venkat 6ba6db4f19 libavutil: Add functions for SMPTE-2094-50 HDR metadata ...

SMPTE-2094-50 is an upcoming standard that is close to being
finalized.

Define a side data type for carrying this metadata. And add
functions for parsing and writing it. This is very similar to
the handling of HDR10+ metadata.

The spec is available here: https://github.com/SMPTE/st2094-50
