Subject: Improve dynamic HDR metadata handling (#13277)

* Add support for bitstream filter to remove dynamic hdr metadata

* Add support for ffprobe's only_first_vframe for HDR10+ detection

* Add BitStreamFilterOptionType for metadata removal check

* Map HDR10+ metadata to VideoRangeType.cs

Current implementation uses a hack that abuses the EL flag to avoid database schema changes. Should add proper field once EFCore migration is merged.

* Add more Dolby Vision Range types

Out of spec ones are problematic and should be marked as a dedicated invalid type and handled by the server to not crash the player.

Profile 7 videos should not be treated as normal HDR10 videos at all and should remove the metadata before serving.

* Remove dynamic hdr metadata when necessary

* Allow direct playback of HDR10+ videos on HDR10 clients

* Only use dovi codec tag when dovi metadata is not removed

* Handle DV Profile 7 Videos better

* Fix HDR10+ with new bitmask

* Indicate the presence of HDR10+ in HLS SUPPLEMENTAL-CODECS

* Fix Dovi 8.4 not labeled as HLG in HLS

* Fallback to dovi_rpu bsf for av1 when possible

* Fix dovi_rpu cli for av1

* Use correct EFCore db column for HDR10+

* Undo outdated migration

* Add proper hdr10+ migration

* Remove outdated migration

* Rebase to new db code

* Add migrations for Hdr10PlusPresentFlag

* Directly use bsf enum

* Add xmldocs for SupportsBitStreamFilterWithOption

* Make `VideoRangeType.Unknown` explicitly default on api models.

* Unset default for non-api model class

* Use tuples for bsf dictionary for now
