See multiple participants on stage
Pin and unpin to stage
Automatic selection of participants to be displayed on the stage filmstrip based on dominant speaker changes
Make Filmstrip a reusable component. Used by MainFilmstrip (old functionality) and the new StageFilmstrip
Rename DominantSpeakerName to StageParticipantNameLabel
Active border now showed only for the dominant speaker (no longer for the pinned participant)
Hide video from the vertical filmstrip for the participants on stage
Update video constraints
Updated pinned indicator

Only calculate for Large Video on the web (otherwise native breaks)
Take preferred max into calculations

Update video quality of large video as well

...when new participant joins.

Repro steps:

1. With p2p disabled and source name signaling enabled.
2. Start a call with 2 tabs.
3. Reload the 2nd tab.
4. The receiver constraints should be updated when the 2nd
   user rejoins. They were not updated, because
   getTrackSourceNameByMediaTypeAndParticipant doesn't have
   the track yet at the time when visibleRemoteParticipants
   are updated. This is fixed by also checking on
   the remote tracks state.

* feat: Use source name based receiver constraints

* add sourceNameSignaling feature flag to config

* move source name specific variables into if block

* ensure sourceName is defined in constraints

* use source name for selectedSources

* use selector to find video track by participant id

* add selector to encapsulate logic to get track source name

* refactor getTrackSourceNameByMediaTypeAndParticipant selector

* rename variable

* move flags config into Feature Flags section

* do not set constraints for local large video

* rename prioritizedSources to onStageSources

* fix flow error

* refactor visibleRemoteTrackSourceNames to a constant

* use selector to get feature flags

* rename selector function

* fix flow error

* add selector for sourceNameSignaling feature flag

The receiver video constraints that are actually sent to the bridge are logged in LJM and need not be logged in the application.

* feat(Filmstrip): Reorder the visible participants in the filmstrip.
The participants are ordered alphabetically and the endpoints with screenshares, shared-videos and dominant speakers (in that order) are bumped to the top of the list. The local participant is also moved to the top left corner as opposed to the bottom right corner.

* squash: Implement review comments.

* squash: store alphabetically sorted list in redux and move shared videos to top.

* squash: Use the DEFAULT_REMOTE_DISPLAY_NAME from interfaceConfig for users without a display name.

The concept of "visible participants" is not yet implemented.

The client now listens for changes to lastN, selectedEndpoints and maxReceiverVideoQuality in redux to trigger sending  bridge message in the new format. This fixes an issue where the stage view <-> tile view changes prompt two receiver constraints messages to be sent, first with the maxHeight update and then with the selected endpoints update.
