selftests/hid: skip tests with HID-BPF if udev-hid-bpf is not installed

udev-hid-bpf is still not installed everywhere, and we should probably
not assume it is installed automatically.

selftests/hid: add tests for the Raptor Mach 2 joystick

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

This tablets gets a lot of things wrong:

- 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

- 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

selftests/hid: tablets: reduce the number of pen state

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.
