pw_assert_basic: add a handler facade layer

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.
