tests: Add basic lifecycle test for mediatek_i2c_spi

This unit test does not require any additional mocks because init
and shutdown of i2c infra was covered in realtek programmer lifecycle.
Default mocking of i2c is sufficient to run a basic lifecycle.

To run the test, config option for the programmer needs to be
enabled explicitly, since by default this programmer is disabled.
