Self-revocation: Call PermissionControllerManager directly from Context

This fixes a bug where self-revocation didn't work in multi-user
settings. Now the correct context is used throughout the call stack and
the permission for the calling user will be revoked.

Also added a checked IllegalArgumentException (previously unchecked
SecurityException) when trying to revoke a permission that is not
currently granted.

Test: manual using two users and
atest android.permission.cts.RevokeOwnPermissionTest
