Use the polyfiller provided by react-native-webrtc.
Drop the permissions API polyfill since we no longer use it in the app
and lib-jitsi-meet already works without it.
With react-native-webrtc 1.89.2 the remote SDP is properly updated before
onaddstream is fired so it's no longer needed.
Also, for readability, IPv6 address synthesis has been moved to a standalone
utils file.
Promise.allSettled is supported from RN 0.63 onwards and is not supported on the current version, use a polyfill for that shims Promise.allSettled if its unavailable or noncompliant.

Ever since https://github.com/facebook/react-native/pull/23674 landed it has
been possible to run timers in the background, assuming your app is allowed to
run in the background already, as is our case. So, stop using the library on
iOS, which will avoid creatring needless backgound tasks.
Move all polyfills to a standalone feature, which gets imported before anything
else in the mobile entrypoint. This guarantees that any further import sees the
polyfilled environment.
