Add actions for calls (#28048)

Add the following actions for use while calling: `Mute`, `Deafen`,
`ShareProject`, `ScreenShare`, `LeaveCall`

We were also interested in adding push-to-talk functionality for mute,
but that will go in a followup PR

Release Notes:

- Call actions (mute/screenshare/etc.) can now be bound to keys and run from the command palette.
