Bug 40044: Fixup Connect screen

Add settings cog

Move TorController's BroadcastReceiver registration into
FenixApplication because TorController misses events when
registration is controlled by HomeFragment.

Initialize tor-android-service with FenixApplication's Context.

Rename localBroadcastReceiver as persistentBroadcastReceiver such that
it isn't confused with the checkIsTorStarted receiver.

Minor improvements

Correct indentation and add restartTor() function

Define enum class for tor's status and define current state using
the enums.

Add access/mutator for bridge information.
