selftests/hid: vmtest.sh: allow finer control on the build steps

vmtest.sh works great for a one shot test, but not so much for CI where
I want to build (with different configs) the bzImage in a separate
job than the one I am running it.

Add a "build_only" option to specify whether we need to boot the currently
built kernel in the vm.

selftests/hid: vmtest.sh: update vm2c and container

boot2container is now on an official project, so let's use that.
The container image is now the same I use for the CI, so let's keep
to it.

selftests: hid: fix vmtests.sh not running make headers

According to commit 01d6c48a828b ("Documentation: kselftest:
"make headers" is a prerequisite"), running the kselftests requires
to run "make headers" first.

Do that in "vmtest.sh" as well to fix the HID CI.

selftests: hid: import hid-tools hid-core tests

These tests have been developed in the hid-tools[0] tree for a while.
Now that we have a proper selftests/hid kernel entry and that the tests
are more reliable, it is time to directly include those in the kernel
tree.

I haven't imported all of hid-tools, the python module, but only the
tests related to the kernel. We can rely on pip to fetch the latest
hid-tools release, and then run the tests directly from the tree.

This should now be easier to request tests when something is not behaving
properly in the HID subsystem.

selftests: hid: make vmtest rely on make

Having a default binary is simple enough, but this also means that
we need to keep the targets in sync as we are adding them in the Makefile.

So instead of doing that manual work, make vmtest.sh generic enough to
actually be capable of running 'make -C tools/testing/selftests/hid'.

The new image we use has make installed, which the base fedora image
doesn't.

selftests: hid: add vmtest.sh

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
