Create app op permission RECEIVE_SANDBOXED_DETECTION_TRAINING_DATA to allow the

privileged assistant apps to receive training data from the sandboxed hotword detection service.

Update the OP_RECEIVE_TRUSTED_PROCESS_TRAINING_DATA to
OP_RECEIVE_SANDBOXED_DETECTION_TRAINING_DATA per API-review feedback.
The naming needs to be consistent with the existing HDS interface
SandboxedDetectionInitializer.

This permission protection level is internal|appop. The default
permission status is PERMISSION_DENIED and the op default mode is
MODE_DFAULT so initial access is PERMISSION_HARD_DENIED.

The access will only be changed by the users via UI toggles:
1) PERMISSION_GRANTED if the user swtich the op mode to MODE_ALLOWED.
2) PERMISSION_HARD_DENIDED if the user swtich the op mode to MODE_ERRORED.
