- Replaced most usages of HidControllerID with HidNpadIdType
- HidControllerID still exists for now, and the following functions
keep accepting it for compatibility with most homebrew:
- hidIsControllerConnected
- hidKeysHeld/Down/Up
- hidJoystickRead
- hidSixAxisSensorValuesRead
- hidControllerIDTo/FromOfficial renamed to ToNpadIdType/FromNpadIdType
- Updated some comments that were left untouched during previous hid refactoring
- Partial internal refactor of hidGetNpadStates*
