Overview
--------
This assert backend implements the ``pw_assert`` facade, by routing the assert
message to the Zephyr assert subsystem. Failed asserts will call:
1) ``__ASSERT_LOC(condition)``
2) If and only if there's a message ``__ASSERT_MSG_INFO(message, ...)``
3) ``__ASSERT_POST_ACTION()``

To enable the assert module, set ``CONFIG_PIGWEED_ASSERT=y``. After that,
Zephyr's assert configs can be used to control the behavior via CONFIG_ASSERT_
and CONFIG_ASSERT_LEVEL_.
