Implement/Stub mnpp:app service and some hid calls (#3131)

* Implement/Stub mnpp:app service and some hid calls

This PR Implement/Stub the `mnpp:app` service (closes #3107) accordingly to RE, which seems to do some telemetry for China region only, so everything is stubbed.

This PR fixes some inconsistencies in the hid service too and stub EnableSixAxisSensorUnalteredPassthrough, IsSixAxisSensorUnalteredPassthroughEnabled, LoadSixAxisSensorCalibrationParameter, GetSixAxisSensorIcInformation calls (closes #3123 and closes #3124).

* Addresses Thog review
