Fix telemetry for collab::ToggleMute and remove unregistered actions (#44432)

This PR removes the actions `collab::ToggleScreenSharing`,
`collab::ToggleMute`, and `collab::ToggleDeafen`. They weren't actually
registered to any behavior, so while it was possible to create a keybind
bound to them, they never actually trigger. I spent ~30 minutes trying
to figure out why I was getting this result for my `"f13":
"collab::ToggleMute"` keybind in the keybind context menu:

/>

(This really threw me for a loop because I was trying to use this as a
known good case to compare against a _different_ action that wasn't
working because I forgot to register it.)

As a side benefit, this enables telemetry for toggling mic mute via
keybind.

Release Notes:

- Fixed telemetry for `collab::Mute`
- Removed unregistered actions `collab::ToggleMute`,
`collab::ToggleDeafen`, and `collab::ToggleScreenshare`
- The correctly-functioning actions `collab::Mute`, `collab::Deafen`,
and `collab::ScreenShare` are recommended instead
