Implement Bluetooth, Btm, Hid and Nsd services and calls. (#761)

- Implement `btdrv` service (IBluetoothDriver).
  Implement call `InitializeBluetoothLe` for initialize events of `bt` service according to RE.

- Implement `bt` service (IBluetoothUser).
  Implement call `RegisterBleEvent` according to RE.

- Add a placeholder for the `btm` service (close #750).

- Implement `btm:u` service (IBtmUser) (close #751).
  Implement call `GetCore` according to RE (close #752).

- Implement `IBtmUserCore` and calls `AcquireBleScanEvent`, `AcquireBleConnectionEvent`, `AcquireBleServiceDiscoveryEvent` and `AcquireBleMtuConfigEvent` according to RE.

- Implement `SetPalmaBoostMode` in `IHidServer` according to RE.

- Add stub for `SetIsPalmaAllConnectable` in `IHidServer` because we will not support Palma devices soon.

- Implement `nsd:a` and `nsd:u` service (IManager) (close #755).
  Implement call `ResolveEx` according to RE (close #756).
  Implement calls `GetSettingName`, `GetEnvironmentIdentifier`, `GetDeviceId`, `DeleteSettings`, `Resolve`, `ReadSaveDataFromFsForTest`, `WriteSaveDataToFsForTest` and `DeleteSaveDataOfFsForTest` according to RE.
