This PR depends on #10633

Description

Adds frontend API calls to allow plugins to register additional canvases/video outputs that will participate in multitrack video configuration generation and multitrack video streams

Motivation and Context

Currently additional views/canvases have to use separate rtmp connections or similar to be streamed, where the multitrack video output allows both multiple renditions of the same view and also different views to be streamed

How Has This Been Tested?

Twitch Enhanced Broadcasting beta

Types of changes

  • New feature (non-breaking change which adds functionality)

  • I have read the contributing document.

rtmp-services: Add Multitrack Video disclaimer
rtmp-services: Populate Twitch specific multitrack video settings
This will be initialized to 0 in various cases, so let's make that
a valid enum value (even if it's not valid in rtmp?)
The status bar doesn't currently own its references to outputs,
which can be a problem if e.g. streaming outputs are released soon
after stream stop. The Multitrack Video output does exactly that,
so the status bar will sometimes try to access an invalid pointer
for updating its stats. Keeping a weak reference around and
upgrading it to collect stats, similar to how the stats window
behaves.
