[PA] Add configuration for iOS binary experiment
To drive the experiment smoothly, we want to make it configurable with
only `//ios` changes.
`enable_ios_corruption_hardening` is now exposed through build overrides
and toggles `enable_partition_lock_reentrancy_check`,
`use_partition_cookie`, `smaller_partition_cookie`, and
`force_disable_backup_ref_ptr_feature`.
