Stop using FDE-related constants from IVold
IVold.ENCRYPTION_STATE_* and IVold.PASSWORD_TYPE_* are values returned
by or accepted by FDE-specific vold methods, which are no longer used.
Stop using these constants so that we can remove them from IVold.aidl.
Notes on specific constants:
- Some constants have @UnsupportedAppUsage. There is no reason why a
non-system app should have been using these. However, to avoid
possibly breaking apps I just left these with hardcoded values.
- StorageManager.CRYPT_TYPE_* are used by
LockscreenCredential.getStorageCryptType(). However, the caller of
this method was removed by an earlier CL, so just remove this method.
- StorageManager.CRYPT_TYPE_* also have a user in
packages/apps/Settings, but it is obsolete code that I'm removing in
another CL.
