The harness was set to ztest, but the sample requires the console
harness to match on the "sample complete" line, its not actually
using ztest.

Add i2c_bus_short fixture to the rtio_loopback sample to ensure it
is only run on boards with the bus shorted. The i2c_bus_short
fixture is also used in the i2c_target_api test suite.

Add sample which clearly and thorougly shows how to use RTIO with
I2C controllers, both synchronously and async, comparing it with
the "standard" I2C API, in an controlled environment. Both the I2C
controller and I2C target are managed by the sample, using loopback
to monitor and control the I2C transfers.
