cleared before confidence, tipswitch and confidence cleared at the same
time, and tipswitch only cleared when touch is actually removed). Also
test two flavors of touch confidence gain (confidence added to a touch
that was "never" confident, and confidence added to a touch that was
previously confident).

To accommodate for legacy devices, we rely on the last state of a
transition to be valid:
for example when we test PEN_IS_OUT_OF_RANGE to PEN_IS_IN_CONTACT,
any "normal" device that reports an InRange bit would insert a
PEN_IS_IN_RANGE state between the 2.
This is of course valid, but this solution prevents to detect false
releases emitted by some firmware:
when pressing an "eraser mode" button, they might send an extra
PEN_IS_OUT_OF_RANGE that we may want to filter.
So define 2 sets of transitions: one that is the ideal behavior, and
one that is OK, it won't break user space, but we have serious doubts
if we are doing the right thing. And depending on the test, either
ask only for valid transitions, or tolerate weird ones.

Turns out that there are transitions that are unlikely to happen:
for example, having both the tip switch and a button being changed
at the same time (in the same report) would require either a very talented
and precise user or a very bad hardware with a very low sampling rate.
So instead of manually building the button test by hand and forgetting
about some cases, let's reuse the state machine and transitions we have.
This patch only adds the states and the valid transitions. The actual
tests will be replaced later.

For the hid-bpf tests to compile, we need to have the definition of
struct hid_bpf_ctx. This definition is an internal one from the kernel
and it is supposed to be defined in the generated vmlinux.h.
This vmlinux.h header is generated based on the currently running kernel
or if the kernel was already compiled in the tree. If you just compile
the selftests without compiling the kernel beforehand and you are running
on a 6.2 kernel, you'll end up with a vmlinux.h without the hid_bpf_ctx
definition.
Use the clever trick from tools/testing/selftests/bpf/progs/bpf_iter.h
to force the definition of that symbol in case we don't find it in the
BTF and also add __attribute__((preserve_access_index)) to further
support CO-RE functionality for these tests.

I haven't imported all of hid-tools, the python module, but only the

So split the final rule in 2, and ensure we compile all dependencies
before.

Similar-ish in many points from the script in selftests/bpf, with a few
differences:
- relies on boot2container instead of a plain qemu image (meaning that
we can take any container in a registry as a base)
- runs in the hid selftest dir, and such uses the test program from there
- the working directory to store the config is in
tools/selftests/hid/results

The Makefile was assuming that headers_install was already done in
the top source directory, and was searching for installed uapi headers
there.
Unfortunately this is not the case and we need to manually call that step.
To do so, reorder the declaration of the variables, and reuses top_srcdir
provided by lib.mk

DYNAMIC_FTRACE_WITH_DIRECT_CALLS is implicit on x86_64 but is still a
WIP on aarm64. Ensure we get it selected to not have any surprises.
