Feature/facebook sdk 16 (#3731)
* Removed AppInvite dialog code for migration to Facebook SDK 16.2.0
* Added support for Facebook SDK 16 in android gradle version.
Still WIP. For build to successed, it seams that gradle version >= 7.2 is required, which requires JDK 11.
But since we already needto update to gradle 8.1 for firebase support, we may want to simply skip that, and do what is required to get gradle 8.1
working as the new standard.
* Updated facebook and FCM support.
Both of these require gradle 8.1, which requires JDK 17, but builder still doesn't support JDK17 in general, so for android builds
we need to set JAVA17_HOME environment variable when performing Android local builds.
* isFriendsInviteSupported now returns false for facebook
