kunit: drop unused kunit* field in kunit_assert

The `struct kunit* test` field in kunit_assert is unused.
Note: string_stream needs it, but it has its own `test` field. I assume
`test` in `kunit_assert` predates this and was leftover after some
refactoring.

This patch removes the field and cleans up the macros to avoid
needlessly passing around `test`.
