serialhdl: Convert queries to use new notify message ack system
...
Convert standard queries to use the acknowledgments of the sent
command to determine if the response was received or not. This also
controls command retransmissions (should the response have been lost).
The tmc_uart.py will continue to use the old mechanism as the tmcuart
responses are not sent synchronously with the query command.

tmc: It's not valid to schedule messages with print_time=0
...
A print_time of zero may translate to a negative clock on a secondary
micro-controller, which would cause an internal error. Change the
code to pass a real print_time or None if it is not needed.
