Implementing RTIO drivers, in theory, should be as simple as the normal
i2c drivers and generally be more consistent across implementations. To
do that some common code that calls driver specific code is needed much
like the venerable spi_context and its helpers.
This adds struct i2c_rtio as well as helpers to perform blocking i2c
transfers, i2c bus recovery, and similar such tasks.

In order to serialize all of the i2c functionality an added op code for
configuring the i2c controller was needed. Thankfully very simple.

- Allow non RTIO i2c drivers to be intermixed with RTIO drivers
- Remove reference to rtio_spsc_drop_all()
- Fix impllicit cast which throws an error with more restrictive
compile flags
