Is your feature request related to a problem? Please describe.

Add support for EXT-X-SESSION-KEY tags in Multi-Variant Playlists.

Describe the solution you'd like

  • Use session keys to begin key selection and key-system access prior to level loading (added in Multi-DRM Support #4930)
  • Key-loader and EME-controller provide some level of mapping between session-keys and level-keys to avoid duplication or parsing of the same keys based on key URI

Additional context

See EXT-X-SESSION-KEY under https://datatracker.ietf.org/doc/html/draft-pantos-hls-rfc8216bis#section-4.4.6.5

#4927

* Throw before licenseXhrSetup if key was removed

* Make key session promise chain more consice
