Created button for Send to breakout room action

Clicking on an item when the popup drawer is displayed would keep it open.
Now clicking on any item should automatically close the drawer.

Popup was also refactored and no longer uses refs.

- long touch on thumbnail opens context menu
- hide context menu icon
- add button for connection info to context menu

* Whitelisted enableSaveLogs

* Added config option to hide Show More on GSM popover

* Updated config option

As per @fremzy, the "Save Logs" feature generates a json
file with a bevy of technical information about the
meeting. This log contains the server name, server IP
address, participant's IP addresses (only in p2p sessions)
e.t.c. While this may be a useful feature for the
admin-like 'moderator', it creates unnecessary exposure
when made readily available to all users in the meeting.

This commit fixes #8036 by a config.js option to enable
the link (disabled by default), thus giving the owner of
the deployment the choice of enabling it or not.

* Add codec reporting to the stats window for connections.
This will report the audio/video codecs, if reported by lib-jitsi-meet.

* feat: Exposes the max enabled resolution in the connection stats popover.
* deps: lib-jitsi-meet@latest

For the most part the changes are taking the "static propTypes" declaration off
of components and declaring them as Flow types. Sometimes to support flow some
method signatures had to be added. There are some exceptions in which more had
to be done to tame the beast:
- AbstractVideoTrack: put in additional truthy checks for videoTrack.
- Video: add truthy checks for the _videoElement ref.
- shouldRenderVideoTrack function: Some component could pass null for the
  videoTrack argument and Flow wanted that called out explicitly.
- DisplayName: Add a truthy check for the input ref before acting on it.
- NumbersList: Move array checks inline for Flow to comprehend array methods
  could be called. Add type checks in the Object.entries loop as the value is
  assumed to be a mixed type by Flow.
- AbstractToolbarButton: add additional truthy check for passed in type.
