HID: Ignore battery for all ELAN I2C-HID devices

Before this change there were 16 vid:pid based quirks to ignore the battery
reported by Elan I2C-HID touchscreens on various Asus and HP laptops.

And a report has been received that the 04F3:2A00 I2C touchscreen on
the HP ProBook x360 11 G5 EE/86CF also reports a non present battery.

Since I2C-HID devices are always builtin to laptops they are not battery
owered so it should be safe to just ignore the battery on all Elan I2C-HID
devices, rather then adding a 17th quirk for the 04F3:2A00 touchscreen.

As reported in the changelog of commit a3a5a37efba1 ("HID: Ignore battery
for ELAN touchscreens 2F2C and 4116"), which added 2 new Elan touchscreen
quirks about a month ago, the HID reported battery seems to be related
to a stylus being used. But even when a stylus is in use it does not
properly report the charge of the stylus battery, instead the reported
battery charge jumps from 0% to 1%. So it is best to just ignore the
HID battery.

HID: input: Fix Apple Magic Trackpad 1 Bluetooth disconnect

When connecting the Trackpad 1 via any bluetooth adapter, the device
disconnects whenever the battery level is queried. It reconnects
again after a few seconds, but it's an incredibly jarring experience
since it will just cut out in the middle of mouse operations.

This patch ignores querying the battery and avoids disconnects.

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.

commit 87562fcd1342 ("HID: input: remove the need for HID_QUIRK_INVERT")
made the assumption that it was the only one handling tablets and thus
kept an internal state regarding the tool.

Turns out that the uclogic driver has a timer to release the in range
bit, effectively making hid-input ignoring all in range information
after the very first one.

Fix that by having a more rationale approach which consists in forwarding
every event and let the input stack filter out the duplicates.
