The only interesting bit is the HAT switch, and we use a BPF program
to fix it. So ensure this works correctly.

More in line with the other test_* files.

We need to slightly change base_device.py for supporting HID-BPF,
so instead of monkey patching, let's just embed it in the kernel tree.

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.

The values are taken from the HID-BPF file.
Basically we are recomputing the array provided there.

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.

few required changes:
- we need to count how many times a udev 'bind' event happens
- we need to tell `udev-hid-bpf` to not automatically attach the
provided HID-BPF objects
- we need to manually attach the ones from the kernel tree, and wait
for the second udev 'bind' event to happen
