[roll third_party/pigweed] pw_stream_uart_mcuxpresso: Add interrupt safe write-only uart stream

Suitable for use in interrupt or fault handlers, it uses the blocking
UART api which spins while tx fifo is drained.

Also tested to be able to take over a UART that was already
initialized elsewhere in the case of a fault handler.
