Separate TelecomManager#isInSelfManagedCall APIs

Instead of consolidating the TelecomManager#isInSelfManagedCall APIs
which combine the cross user logic with the ability to also specifiy a
user handle, create two separate APIs to handle this. One will allow the
caller to specify a user handle while the other will allow them to
specify if calls should be verified across all users.

Ensure that if the user handle specified isn't the caller or that
interacting across users is defined in the parameter, that the
permission check is enforced properly. Otherwise, ensure that the user
handle being verified is always the caller.
