However, the first few lines of kunit/start.rst never got updated, oops. Fix this by telling people to run kunit.py first, which will automatically generate the .kunit directory and .kunitconfig file, and then edit the file manually as desired.

The same thing happens if you did --kunitconfig_add=CONFIG_KASAN=y [1] and then ran again without it. Your new run will still have KASAN. The reason is that kunit.py won't regenerate the .config file if it's a superset of the kunitconfig. This speeds it up a bit for iterating. This patch adds an additional check that forces kunit.py to regenerate the .config file if the current kunitconfig doesn't match the previous one. What this means: * deleting entries from .kunitconfig works as one would expect * dropping a --kunitconfig_add also triggers a rebuild * you can still edit .config directly to turn on new options We implement this by creating a `last_used_kunitconfig` file in the build directory (so .kunit, by default) after we generate the .config. When comparing the kconfigs, we compare python sets, so duplicates and permutations don't trip us up. The majority of this patch is adding unit tests for the existing logic and for the new case where `last_used_kunitconfig` differs.

Move it alongside the other KUnit configs in tools/testing/kunit/configs, and give it a name which matches the existing all_tests.config and broken_on_uml.config files. Also update the Getting Started documentation to point to the new file.
