Implement vibrations (#2468)
* First working vibration implementation

* Fix Infinite Rumble in SDL2Mouse

* Stop ignoring one vibValues every 2

* Remove RumbleInfinity as suggested

* Reworked all the vibration handle / calculation

* Revert HidVibrationDevicePosition changes

* Add UI to enable and tune rumble

* Remove some stub logs

* Add PlayerIndex in rumble debug log

* Fix all requested changes

* Implements hid::GetVibrationDeviceInfo

* Better implements HidVibrationValue.Equals/GetHashCode

* Added requested changes from code review

* Last fixes from review

* Update configuration file version for rebase
