tests: Add tests for HDR Static Metadata encoding/decoding and equality

Browse Source 
We have the drm/InfoFrame encoding and our MetaOutputHdrMetadata
encoding. Check that we can correctly convert between each other by
doing a encode/decode and decode/encode roundtrip and then checking for
equality.
