More flexible API enforcement policy support.

This CL adds the ability to configure which banned API lists to enforce,
defined by new enum hiddenapi::ApiEnforcementPolicy. Currently, the policy
can be set at zygote fork time, but not at dex optimization time where
blacklist enforcement is still assumed. As such, making the policy more
strict will not work as expected yet. This will be improved in a follow up
CL.

Test: art tests pass
