Extracted common SPI RTIO operations from the spi_mcux_lpspi driver
into spi_rtio, which should be common across RTIO drivers.
Tested with spi_loopback with and without CONFIG_SPI_RTIO. Ran on
mimxrt1010_evk.
Also, verified the other SPI RTIO driver (spi_sam) is not broken by
these changes (tested building for target: robokit1 with the same
conditions as above).

Provides a macro and submit API for SPI drivers to support RTIO.
A copy function enables compatibility with the existing blocking API
and very easily the existing async API as well.
