hidapi: Disable hidapi LG4FF on windows (#14762)

Browse Source 
hid.dll simply cannot send 7 bytes reports unlike other platforms

It enforces full length repots of 17 from the device's descriptor,
which does not work on the device.

This breaks ffb and led control, so we disable this by default on
windows.
