Add unit tests to verify that warning backtrace suppression works. Tests cover both API forms: - Scoped: kunit_warning_suppress() with in-block count verification and post-block inactivity check. - Direct functions: kunit_start/end_suppress_warning() with sequential independent suppression blocks and per-block counts. Furthermore, tests verify incremental warning counting, that kunit_has_active_suppress_warning() transitions correctly around suppression boundaries, and that suppression active in the test kthread does not leak to a separate kthread. If backtrace suppression does _not_ work, the unit tests will likely trigger unsuppressed backtraces, which should actually help to get the affected architectures / platforms fixed.
