houchenyao 7a31b93fa3 unit-test-app: support multiple devices test cases:
current unit-test-app don't support test components need to communicate
with each other (like GPIO, SPI ...). Now we add multiple devices mode
to unit test app, support writing and running test with multiple DUTs.

please refer to `docs/api-guides/unit-tests.rst` for detail.

* @brief wait for signals.
*
* for multiple devices test cases, DUT might need to wait for other DUTs before continue testing.
* As all DUTs are independent, need user (or test script) interaction to make test synchronized.
*
* Here we provide signal functions for this.
* For example, we're testing GPIO, DUT1 has one pin connect to with DUT2.
* DUT2 will output high level and then DUT1 will read input.
* DUT1 should call `unity_wait_for_signal("output high level");` before it reads input.
* DUT2 should call `unity_send_signal("output high level");` after it finished setting output high level.
* According to the console logs:
*
* DUT1 console:
*
* ```
* Waiting for signal: [output high level]!
* Please press "Enter" key to once any board send this signal.
* ```
*
* DUT2 console:
*
* ```
* Send signal: [output high level]!
* ```
*
* Then we press Enter key on DUT1's console, DUT1 starts to read input and then test success.
