* Let `[ignore] case` return to freedom
1) Because this test uses its own ISR, we need to release it with `esp_intr_free` instead of `pcnt_isr_service_uninstall`.
2) `pcnt_evt_queue` needs to be created before the interrupt is registered and needs to be released at the end of each case.
* Add test support for ESP32S2
* Support chip internal connection, no external wiring required.
