Damien George 38e7b842c6 ports: Implement simple write polling for stdout. ... This is a best-effort implementation of write polling. It's difficult to do correctly because if there are multiple output streams (eg UART and USB CDC) then some may not be writeable while others are. A full solution should also have a return value from mp_hal_stdout_tx_strn(), returning the number of bytes written to the stream(s). That's also hard to define. The renesas-ra and stm32 ports already implement a similar best-effort mechanism for write polling. Fixes issue #11026.
