Controller Input handling refactoring (#1751)

Browse source 
* This should fix issue #1374 in Linux

Changes:
- Bind buttons by detecting the transition from down to up.
- Bind axis by detecting movement from value higher than 50% to a value lower than 50%.

Caveats:
- I have tested only with DS3 in Linux (Fedora 32).
- ZL and ZR detection works by accident. This code doesn't take negative axis into account.
  The reason it works is because axis are managed in absolute value. So when pressing ZL/ZR
  axis value goes from -1 to 1 (or 1 to 0 and back to 1) and this hits the axis detector.
- Likely I have broken all the other controllers xD (testing needed).

* Assign keyboardPressed

* Make a more robust detection of pressed buttons when using a controller

* Add interface to bind buttons from Joystick and Keyboard

* Fix style issues after code review by @AcK77  (Thanks!)

* Move new classes to Ryujinx.Ui.Input namespace

* Use explicit types instead of var

* Update Ryujinx/Ui/Input/JoystickButtonAssigner.cs
