serialhdl: Convert queries to use new notify message ack system

Browse source 
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.
