This tablets gets a lot of things wrong:
- the secondary button is reported through Secondary Tip Switch
- the third button is reported through Invert

We need to add some out of proximity intermediate state when moving
back and forth with the eraser mode as it can only be triggered by
physically returning the pen, meaning that the tolerated transitions
can never happen.

Those tablets don't need special initialization, but are reporting
the events with the wrong usages:
- tip switch is used when the eraser should be used
- eraser is used instead of the secondary barrel switch

Add tests for those so we don't regress in the future.

Currently we set x/y tilt to 0 to not trigger the bpf program

All the *_WITH*BUTTON states were almost identical except for the
button itself.

I need to add a new device with a third button, and adding a bunch of
states is going to be quite cumbersome.

So convert the `button` parameter of PenState as a boolean, and store
which button is the target as an argument to all functions that need it.

This tablets gets a lot of things wrong:
- the secondary button is reported through Secondary Tip Switch
- the third button is reported through Invert

Fortunately, before entering eraser mode, (so Invert = 1),
the tablet always sends an out-of-proximity event.
So we can detect that single event and:
- if there was none but the invert bit was toggled: this is the
  third button
- if there was this out-of-proximity event, we are entering
  eraser mode, and we will until the next out-of-proximity.

When using the XBox Wireless Controller Elite 2 over Bluetooth,
the device exports the paddle on the back of the device as a single
bitfield value of usage "Assign Selection".

The kernel doesn't process those usages properly and report KEY_UNKNOWN
for it.

SDL doesn't know how to interprete that KEY_UNKNOWN and thus ignores the
paddles.

Given that over USB the kernel uses BTN_TRIGGER_HAPPY[5-8], we
can tweak the report descriptor to make the kernel interprete it properly:
- we need an application collection of gamepad (so we have to close the
  current Consumer Control one)
- we need to change the usage to be buttons from 0x15 to 0x18

This pen is compatible with multiple Wacom tablets, but we only add support
for the Intuos Pro 2 M, as this is the one our user reported the bug
against.

We can not generically add all compatible Wacom tablets as we are
writing the offsets by hand.

The point of this HID-BPF program is to work around a firmware limitation
where the pressure is repeated every other report.
Given that we know this will happen, we can change the first new pressure
information with the mean compared to the previous one. This way we
smooth the incoming pressure without losing information.

This commit adds a fix for XPPen Artist 24 where the second button on
the pen is used as an eraser.

It's a "feature" from Microsoft, but it turns out that it's actually
painful for artists. So we ship here a HID-BPF program that turns this
second button into an actual button.

Note that the HID-BPF program is not directly loaded by the kernel itself
but by udev-hid-bpf[0]. But having the sources here allows us to also
integrate tests into tools/testing/selftests/hid to ensure the HID-BPF
program are actually tested.

Turns out that the code can handle a greater range, but the data stored
can not. This is problematic on the Raptor Mach 2 joystick which
logical max is 239. The kernel interprets it as `-15` and thus ignores
the Hat Switch handling.
