Squashed merge of master-sim into master.

Includes the following commits:

==

Let phone process bind to EuiccService implementation.

==

Implement EuiccManager actions through a dispatcher.

The dispatcher is a trampoline activity which forwards the given
action to the highest-priority LUI implementation after performing the
necessary prerequisite checks. It has priority=1000, which means no
APK other than those bundled with the system can supercede it.

==

Add eUICC UI into Mobile Network Setting Screen

Add a preference in Mobile Network Setting Screen to start the
eUICC settings. This preference will only be available when
EuiccManger#isEnabled is true.
