zephyr: Add TCS3400 emulator
Add TCS3400 emulator which is emulated device on i2c bus. Emulator
properties can be defined using device tree or runtime TCS emulator API.
It allows to set custom handlers for write and read messages. Emulator
is able to convert internal values to register values that can be
obtained by driver through i2c interface. Conversion takes current state
set by driver into account (gain and data acquisition time).
