zephyr: Add BB retimer emulator
Add BB retimer emulator on i2c bus. Emulator properties can be defined
using device tree or runtime emulator API. Emulator checks if RO
registers and reserved bits are accessed correctly. API allows to set
custom read/write i2c messagess handlers to emulate complex behaviour.
