Handle permission check for multi-active SIMs devices.

For download and switch, if the caller can manage (has carrier privilege)
on any active sub on any other slots && the caller can manage the active
sub on the target slot or there is no active sub on the target slot, we
allow the caller to continue download. Otherwise, we require user consent.
For getting EID, we now check whether the caller has privilege on the
target card with the given cardId.
Other logic including the logic for single-active slot still keep the
same.
Also, open disable sub (switch to empty sub) to privileged carrier apps
instead of just system.
