* ref(large-video): reactify background

This is pre-requisite work for disabling the background on
certain browsers, namely Firefox. By moving the component
to react, and in general encapsulating background logic,
selectively disabling the background will be easier.

The component was left for LargeVideo to update so it can
continue to coordinate update timing with the actual large
video display. If the background were moved completely into
react and redux with LargeVideo, then background updates would
occur before large video updates causing visual jank.

* fix(large-video): do not show background for Firefox and temasys

Firefox has performance issues with adding filter effects on
animated elements. On temasys, the background videos weren't
really displaying anyway.

* some props refactoring

Instead of passing in classes to LargeVideoBackground, rely on
explicit props. At some point LargeVideo will have to be reactified
and the relationsihp between it and LargeVideoBackground might
change, so for now make use of props to be explicit about
how LargeVideoBackground can be modified.

Also, set the jitsiTrack to display on LargeVideoBackground to
null if the background is not displayed. This was an existing
optimization, although previously done with pausing and playing.

* squash: use newly exposed RTCBrowserType

* squash: rebase and use new lib browser util

* squash: move hiding logic all into LargeVideo

* squash: remove hiding of background on stream change. hopefully doesnt break anything

Passing around of the component was used when there were two
independent Notification components. Now that there is only
one Notification component, it is not necessary to pass
around the component.

Ga tweaks

This is only implemented for mobile at the moment, since web doesn't handle
visibility within the Filmstrip component yet, so this should be added right
then, too.

The package jitsi-meet-prosody was missing from the list of packages.

Bumps lib-jitsi-meet to latest. There was a problem that jitsi-meet build fail if anybody touches package.json (including PR testing), this happen after start using custom strophe.js from github:jitsi/strophejs.
The error:

Without strophejs-plugin-disco jitsi-meet builds but on runtime loading fail with:

FIXME: We should remove this once strophe.js releases new version and we are back to the official one inside lib-jitsi-meet.

Story time.  Currently the app can be started in 4 ways:

- just tapping on the icon
- via a deep link
- via a universal link
- via the phone's recent calls list

The last 3 options will make the app join the specified room upon launch. React
Native's Linking module implements the necessary bits to handle deep or
universal linking, but CallKit is out of its scope.

In order to blend any type of app startup mode, a new LaunchOptions module (iOS
only) exports a getInitialURL function, akin to the one in the Linking module,
but taking CallKit instents into consideration. This function is then used to
make app startup with a URL consistent across all different modes.

* chore: Updates lib-jitsi-meet to 5f8c0a662a

* squash: revert changes to package-lock.json except for the lib-jitsi-meet version change.

* Handles connection failed event details (passing them to analytics).

* Fixing comments.

* Updates depending versions to be able to test.

* Fixing comments.

* Fixes wrong jsdoc.

It's detected based on a size threshold.

We started on the way to responsive UI and its design with aspect ratio
and keeping the filmstrip on the short side of the app's visible
rectangle.

Shortly, we're going to introduce reduced UI for Picture-in-Picture. And
that's where we'll need another dimensions-based detector akin to the
aspect ratio detector.

While the AspectRatioDetector, the up-and-coming ReducedUIDetector, and
their base DimensionsDetector are definitely separate abstractions and
implementations not mixed for the purposes of easy extensibility and
maintenance, the three of them are our building blocks on top of which
we'll build our responsive UI.

Factor out the dimensions detection login into a DimensionsDetector component.

Turns out this was a bit more involved than I originally thought due to an
interesting (corner) case: IFF the user was never asked about microphone
permissions and the call starts with audio muted, unmuting from the CallKit
interface won't work (iOS won't show the prompt, it fails immediately) and we
need to sync the mute state back.

Instead of having visible and visibility and setToolboxVisible and
setFilmstripVisibility, have only visible as a name.

It may happen that such action is fired while joining.

If the view gets resized to a 1:1 aspect ratio, remember the previous mode to
avoid flickering when going back to a larger size or different aspect ratio.

Add URL validation and larger distance behind the back button

Fixes: #2377 #2267 #2158

The current notification for starting muted is 2 minutes, which
may seem like "forever" so reduce it to dismiss faster.

If config.enableUserRolesBasedOnToken is true, only let moderators
and non-guests modify the password. Otherwise, only let moderators
edit the password.

fix(recommended-browsers): Fix link

chore(lib-jitsi-meet): Update the version.

Load all of them as imports, so the packager includes them in the bundle. Then
register them with the i18next library.
