Add example_init_test_suite to allow for testing the feature of running
test suites marked as init to indicate they use init data and/or
functions.

This suite should always pass and uses a simple init function.

This suite can also be used to test the is_init attribute introduced in
the next patch.

Can we make the actual test function __init as well? I don't think it
should be _necessary_ for this to work, but I'd like us to have the
option of entire tests being marked __init, and so discarded after
boot.

This seems to work here if the test is marked __init, and the
example_init_test_cases and example_init_test_suite are marked
__initdata.

But, as mentioned in the previous patch, that might not work if we
need to ensure example_init_test_suite and other metadata still
exists. So maybe we can document that here?

Otherwise, looks good.
