Add manifest broadcasts for profile (un-)available.

This mean both switch on/off and add/remove profiles.

The broadcasts already exists for registered receivers, this adds them
for manifest receivers with INTERACT_ACROSS_PROFILES permission and
crossProfile attribute.

The MANAGED_PROFILE_REMOVED broadcast is sent to all application with
android:crossProfile="true". Any cross profile app may be impacted, and
there is no possible transfer of information as the account is already
deleted at the time the signal is emitted.
