ESP32-C6, at least: board.UART() or busio.uART() on GPIO16 and GPIO17 is returning "Invalid pins".

Discovered by a user in Discord. I'm debugging this: may have to do with HP vs LP UARTs and which pins work for each kind. Also found there is incomplete cleanup when the busio.UART() constructor raise an exception.
