HID: input: Support devices sending Eraser without Invert
Some digitizers (notably XP-Pen Artist 24) do not report the Invert
usage when erasing. This causes the device to be permanently stuck with
the BTN_TOOL_RUBBER tool after sending Eraser, as Invert is the only
usage that can release the tool. In this state, Touch and Inrange are
no longer reported to userspace, rendering the pen unusable.
Prior to commit 87562fcd1342 ("HID: input: remove the need for
HID_QUIRK_INVERT"), BTN_TOOL_RUBBER was never set and Eraser events were
simply translated into BTN_TOUCH without causing an inconsistent state.
Introduce HID_QUIRK_NOINVERT for such digitizers and detect them during
hidinput_configure_usage(). This quirk causes the tool to be released
as soon as Eraser is reported as not set. Set BTN_TOOL_RUBBER in
input->keybit when mapping Eraser.
Fixes: 87562fcd1342 ("HID: input: remove the need for HID_QUIRK_INVERT")
