driver: spi: MAX32 add RTIO support plus refactor

Implements the SPIO RTIO API. Refactors internal transcive
fucntios to work with both existing SPI API and RTIO functions.

When SPI_RTIO is enabled the spi_transcieve call translates
the request into an RTIO transaction placed in the queue
that device will execute.

Include the latest refacor changes of RTIO.
