Move carrier privilege status checks to CarrierPrivilegesTracker.

All query methods to get the status of a package or UID (including the
aggregate "get all privileged packages" methods) now use
CarrierPrivilegesTracker as the source of truth. The remaining
Uicc{Port,Profile,CarrierPrivilegeRules} redundancies will be cleaned up
in a follow-up CL.

This implicitly adds a caching layer that should result in noticeable
performance increases, since PackageManager is only queried ~once
(typically at boot) rather than every time one of these methods is
called.

This CL also move the support of enabling hidden carrier apps on
carrier privilege granting from UiccCarrierPrivilegeRules/UiccProfile
to CarrierPrivilegesTracker.
