Check Carrier Privilege on Hidden Subs

Browse Source 
When calling CheckCarrierPrivilegeForAnySubId the
hidden subscriptions were not being taken into account
due to getAllActiveSubscriptionIds being a public method
that intentionally ignores hidden subscriptions.

NOTE: This is identical to ag/8193293, except that the
SubscriptionManager modifications don't make
getActiveSubscriptionIdList() static (it was causing test failures). A
further bug can be pursued to make everything static all at once.

Bug: 135684437
Test: manual
