CTS: Test NFC sharing user restriction

- Test for UserManager#DISALLOW_OUTGOING_BEAM user restriction
- Added test for whether BeamShareActivity is resolved in
Intent.ACTION_SEND
- The beam-triggered path is not yet tested because it need to be
triggered manually. It should be added to CtsVerifier in a separate
commit
