Let modules obtain target component of PendingIntent

- Media module needs to extract the component that a PendingIntent will
be sent to.

Currently, the code is bundled, so they're using the hidden
PendingIntent.getIntent() API, but we really do not want to make it @SystemApi.

So instead, adding a way to obtain the resolve information instead.

- !!Media should make sure the resolved components are actually owned by the
same package that called the API!!
