test_app: Extend panic app to include memprot-related tests
- Add support for esp32s2, esp32c3 and esp32c2 for the `memprot`-related tests
- Preliminary support for esp32s3 has also been added,
  the test app will be enabled for esp32s3 later when
  the memprot-related issues are fixed.
- Override panic handler to dump the violation intr status
  - Dump the `memprot` violation registers before calling the
    real panic handler
  - Handle `Illegal Instruction` exception in case of memprot permission violation
    * In esp32c3 with `memprot` enabled, if we try to execute arbitrary code
      from RTC_FAST_MEM we get an `Illegal Instruction` exception from the panic
      handler rather than a `Memory Protection Fault`.
    * This is because the Illegal Instruction interrupt occurs earlier than the
      memory protection interrupt due to a higher interrupt latency.
