pw_assert: Add option to pw_assert_basic to call _Exit

Add option to exit the pw_assert_basic backend by calling std::_Exit to
exit the program without running atexit handlers or destructors.

This is needed in the following two cases:

In the case of using pw_build's `wrap_abort`, and the `pw_assert_basic`
default backend, assert failures would infinitely recurse calling abort.

In addition, when not using `wrap_abort` some C library implementations
will attempt to take mutexes out, which shouldn't be done in a crash
handler as it may deadlock.
