Fix package visibility broadcast regression

Sending broadcasts are not restricted by the package visibility of the
calling package. This is achieved by clearing the Binder calling
identity in several top-level broadcast sending APIs.

ag/15315839 introduced intent filter matching enforcement, which
requires the real calling UID to be used for evaluation. This caused
regression in broadcast package visibility.
