HID: uclogic: Add HID_QUIRK_HIDINPUT_FORCE quirk
[ Upstream commit 3405a4beaaa852f3ed2a5eb3b5149932d5c3779b ]
Commit f7d8e387d9ae ("HID: uclogic: Switch to Digitizer usage for
styluses") changed the usage used in UCLogic from "Pen" to "Digitizer".
However, the IS_INPUT_APPLICATION() macro evaluates to false for
HID_DG_DIGITIZER causing issues with the XP-Pen Star G640 tablet.
Add the HID_QUIRK_HIDINPUT_FORCE quirk to bypass the
IS_INPUT_APPLICATION() check.
