Update ESP-IDF to 5.2.1

[tannewt]

This updates the underlying I2C API and allocates memory. So, I switched busio.I2C to using a finalizer for reset instead of bulk reset.

I tried this on my memento. It runs but the camera stops working. I'll look tomorrow if @jepler doesn't get to it first.

Still draft because it needs: adafruit/esp32-camera#8

Just out of curiosity, why is 120m unstable?
With ESP-PSRAM64(H) chips, I didn't have a single crash due to psram.
It's a supported frequency according to the datasheet. Is there an idf timing issue?

From here:

           - Octal PSRAM 120 MHz is an experimental feature, it works when
             the temperature is stable.

               Risks:
                   If your chip powers on at a certain temperature, then after the temperature
                   increases or decreases by approximately 20 Celsius degrees (depending on the
                   chip), the accesses to / from PSRAM will crash randomly.

Ok, @dhalbert this is ready for review.

Port waveshare_esp32s2_pico still has CIRCUITPY_ESP_PSRAM_FREQ = 120m.
I ran a string search just in case there are others, but no.

I left that in because it is marked as quad not octal.

OK, looks good! Looking forward to 9.1.0-beta.0!
