selftests/hid: tablets: add a couple of XP-PEN tablets
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
