Splits up the pw_assert_basic module to add a facade layer to allow a user to provide a custom pw_assert_basic_HandleFailure() implementation. The existing handler, previously named pw_Crash(), was moved to a basic_handler facade which mirrors the pw_cpu_exception structure and naming. Unlike pw_cpu_exception, pw_assert_basic defaults to the basic_handler backend. This refactor should allow users, especially during initial bringup, to trivially bring up assert support with target specific handlers with less code duplication and complications. Note that pw_assert_basic is still not recommended for production use as it is rather heavy weight, we strongly recommend using tokenized asserts.
