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

* fix(audio-only) Do not enable video automatically when audio-only is disabled.

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.

* feat(base): created Button.tsx and IconButton.tsx

Move all sheets to render in a new container which uses FullWindowOverlay, which allows rendering above presentation controllers on iOS.

In the past we used a PanResponder to detect user gestures in the sheet
to show a reduced version or a full-height version of it, and also to
close it.

There is an obvious conflic between the gestures and scrolling, which
didn't work all that great, but we could live with it.

After reactions were introduced we no longer rendered the 2 different
heights, so that functionaligy stopped being used but the PanResponder
still remained there.

This commit removes it completely and sets a max height of 75% on any
BottomSheet, so any tap outside will close it.

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

- opens as a modal
- lastn is 0, mutes local video while open
- long press to talk
- and more

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.

Just like the web.

- 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

Fixed issue on DialogPortal where the content would flash to the initial position then move to the correct position

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

Update Android build to support gif
Use GIF format instead of animated webp
Show GIFs in chat messages
Display GIF over tile
Add Giphy button in reactions menu
Added Giphy dialog
Fix isGifMessage to also allow upper case

* 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.

Show GIF menu in reactions menu
Search GIFs using the GIPHY API
Show GIFs as images in chat
Show GIFs on the thumbnail of the participant that sent it
Move GIF focus using up/ down arrows and send with Enter
Added analytics

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.

Added toggle button in overflow menu
Created video menu with connection info and self view toggle buttons for local participant

The audio route selector is how in the header.

The mute options are in the participants pane, with the rest of the
moderation controls.

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

- add possibility to allow execution of the button's routine besides triggering
`toolbarButtonClicked` API event
- keep backwards compatibility
- get rid of `ToolbarButton`
