HID: logitech-hidpp: Detect hi-res scrolling support

Rather than relying on a never-ending stream of patches for quirks.

This change will detect whether HID++ 1.0 hi-res scroll, HID++ 2.0
hi-res scroll or HID++ 2.0 hi-res scroll wheel is supported, and enable
the feature without the need for quirks.

Tested on a Logitech M705 mouse that was unsupported before this change.
