Implement SInput Device Support (#13343)

Browse Source 
This implements a new SDL HID driver for a format developed by Hand Held Legend for their gamepad devices called SInput

Devices that are supported by this change with well-defined mappings

GC Ultimate ( https://gcultimate.com )
ProGCC ( https://handheldlegend.com/products/progcc-kit-wireless-wired-bundle )

The SInput format is documented here: https://github.com/HandHeldLegend/SInput-HID
