tools: Initially add i2c tool and mock
The power-utils will invoke i2c get/set commands to the i2c device for
PSU code update.
Create a separated i2c tool because it is logically standalone and could
be shared for other utils.
Also add an I2CInterface and its mock to make it easier to test when
developing i2c related operations.
