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.

For anyone on a recent version of Fedora that wants to test it, those

Using this kernel I tested several Logitech mice - an MX Master 3, which
already supported hi-res scrolling in Linux; an M310 and an M185, which have
features but no feature for hi-res scrolling; and an old-style M510, which
does not have features. I used evtest to show the events that were
generated. For these mice the patch does not produce any change in events
generated, as expected, both REL_WHEEL and REL_WHEEL_HI_RES events.
