uart: Improve robustness of query API result processing
Since either of the UART signals (RX, TX) is optional, and in the absence of Decoder.wait() conditions that "will never match", we cannot construct a constant layout. Instead we need to explicitly keep track of which item in the list of wait conditions corresponds to which signal. Once the index in the list of wait conditions is known, inspection of samples can depend on the Decoder.matched[] attribute. Before this change, redundant reached_bit() checks kept us from processing samples that should not have been inspected. Tests pass before and after this very commit.
