Add autofill service setting in managed profile

Previously, there was no way to change the autofill service of the
personal and managed profile independently. After 'uncloning' the
setting in ag/4666330, we now introduce a separate UI control
for each profile.

BUG: 38033559
Test: Tested manually by setting up a work profile and verifying that
the setting can be changed independently. Also verified that the
additional UI does not show without a managed profile.
