Fix direct keyboard not working when using a Controller. (#6716)

* Fix direct keyboard not working when connected with a controller

- Pass KeyboardDriver to NpadController.GetHLEKeyboardInput().
- Always fetch all keyboards if Direct Keyboard is turned on.
- Remove unnecessary return null.

* Get Keyboard Inputs outside of the controller loop.

- Moved GetHLEKeyboardInput outside of the controller loop.
- Made GetHLEKeyboardInput public static from public

* Removed extra newline

* Update src/Ryujinx.Input/HLE/NpadManager.cs
