Jakob Hasse 8df4625c84 refactor(esp_event): improved esp_event unit tests
* Decomposed tests into atomic unit tests
* Made tests less time-dependent, hence more robust
  on different platforms (ESP32, QEMU, Linux)
* Ported most of the tests to linux
* Removed some redundant tests
* Fixed bug the tests discovered
* Simplified parts of the tests to be more clear
* Partially used C++ to simplify setup/teardown
* Unified setup/teardown in general
