To be able to add more testing documentation move the testing
section to it's own page.

No change on the documentation itself.

Testing
=======
There are the tests that come from the examples in the Rust documentation
and get transformed into KUnit tests. These can be run via KUnit. For example
via ``kunit_tool`` (``kunit.py``) on the command line::
./tools/testing/kunit/kunit.py run --make_options LLVM=1 --arch x86_64 --kconfig_add CONFIG_RUST=y
Alternatively, KUnit can run them as kernel built-in at boot. Refer to
Documentation/dev-tools/kunit/index.rst for the general KUnit documentation
and Documentation/dev-tools/kunit/architecture.rst for the details of kernel
built-in vs. command line testing.
Additionally, there are the ``#[test]`` tests. These can be run using
the ``rusttest`` Make target::
make LLVM=1 rusttest
This requires the kernel ``.config`` and downloads external repositories.
It runs the ``#[test]`` tests on the host (currently) and thus is fairly
limited in what these tests can test.
