Change Bluetooth HID Profile Name (1/11)
Make the Bluetooth HID profile name consistent with the Bluetooth HID service
name.
BluetoothInputHost → BluetoothHidDevice
BluetoothInputDevice → BluetoothHidHost
IBluetoothInputHost → IBluetoothHidDevice
IBluetoothInputDevice → IBluetoothHidHost
BluetoothProfile.INPUT_HOST → BluetoothProfile.HID_DEVICE
BluetoothProfile.INPUT_DEVICE → BluetoothProfile.HID_HOST
Bug: 68055651
Test: make
