Add the ability (for moderators) to end the meeting for everyone.

Convert files that use material-ui to TS (needed for material-ui upgrade)

The new behavior is as follows:

IF a user has a token and `features` is not set, we treat it as if the
feature was enabled.

IF a user has a token and `features` is set, we check if the feature
name has a value of "true".

`isJwtFeatureEnabled` also provides a way to specify the default value
in case there is no token.

In multi-stream mode, both camera and desktop streams are available at the same time. Virtual backgrounds can be applied to the camera stream while screensharing is in progress.

The functionality is still accessible in the participants pane, with all
moderation controls.

It's about to become very confusing, since we are going to add actual
local recordings with video.

This feature was never fully finalizeed since it required manual
processing of the files, as they were not uploaded anywhere.

In addition, unless one opens the local audio device without any audio
processing first, any tracks opened later will have audio proceessing
turned on, something not desirable for the scenario this feature was
designed for in the first place: podcasts.

This feature will likely come back as a JaaS demo / MVP where the local
recording is made outside of the Jitsi Meet iframe.

- if hiddenPremeetingButtons is undefined, toolbarButtons overwrite decides what buttons to show
- if hiddenPremeetingButtons is empty array, all buttons are show on premeeting screen regardless of toolbarButtons
- if hiddenPremeetingButtons hides some buttons, only those buttons will be hidden regardless of toolbarButtons overwrite

refactor overflow menu to use ContextMenu component
refactor toolboxItem to use ContextMenuItem when needed

* feat(multi-stream-support) Add screenshare as a second video track to the call.
This feature is behind a sendMultipleVideoStreams config.js flag. sourceNameSignaling flag also needs to enabled. Sending multiple tracks is currently supported only on endpoints running in unified plan mode. However, clients with source-name signaling enabled and running in plan-b can still receive multiple streams .

* squash: check if there is an existing track before adding camera/desktop

* squash: enable multi-stream only on unified plan endpoints.

Move label to LargeVideo so that's it's centred in the view instead of the whole screen
Move vertical filmstrip max width calculation to a function and use it to set the large video width

They don't render the toolbar so there is more space available.

The reason this commit does that is because getToolboxHeight will now
always be 0 for recorders.

Also, ignore the toggle screenshare shortcut when the video sender limit is reached.

`toolbarButtonClicked` API event
- keep backwards compatibility
- get rid of `ToolbarButton`
