[wlan][mlme] Fix AP associate result code to status code mapping

The fidl_mlme::AssociateResultCodes values should trivially map one-to-one
with StatusCode values. Prior to this change, the mapping was one-to-one
but not quite trivial. The mapping of AssociateResultCodes::RefusedReasonUnspecified
is changed to StatusCode::REFUSED instead of StatusCode::DENY_OTHER_REASON.

Added an additional test of handle_mlme_assoc_resp() that tests the
new mapping.

Test: fx test wlan-mlme-tests
