Commit fadb08e7c7 ("kunit: Support for Parameterized Testing")
introduced support but lacks documentation for how to use it.
This patch builds on commit 1f0e943df6 ("Documentation: kunit: provide
guidance for testing many inputs") to show a minimal example of the new
feature.

usage.rst goes into a detailed section about faking out classes, but
currently lacks wording about how one might idiomatically test a range
of inputs.
Add a new chapter for "Common Patterns" and group "Isolating behvaior"
and this new section under there.
Give an example of how one might test a hash function via macros/helper
funcs and a table-driven test and very briefly discuss pros and cons.
Also highlight the KUNIT_EXPECT_*_MSG() variants (that aren't mentioned
elsewhere [1]) which are particularly useful in these situations.
It is also criminally underused at the moment, only appearing in 2
tests (both written by people involved in KUnit).
