skhdr::Metadata: Add CLLI and MDCV metadata and parsing
Add the skhdr namespace and add the skhdr::Metadata structure, which
includes all HDR metadata.
Add the structures skhdr::ContentLightLevelInformation and
skhdr::MasteringDisplayColorVolume, with code to parse and print, and
tests for this.
Of note is that this mirrors several gfx::HDRMetadata structures. The
goal is to replace those structures with SkHdrMetadata structures.
