esp32: Workaround native code execution crash on ESP32-S2.
Seemingly ESP-IDF incorrectly marks RTC FAST memory region
as MALLOC_CAP_EXEC on ESP32-S2 when it isn't. This memory is
the lowest priority, so it only is returned if D/IRAM is exhausted.
Apply this workaround to treat the allocation as failed if it gives us
non-executable RAM back, rather than crashing.
This work was funded through GitHub Sponsors.
