Update to new I2C API in ESP-IDF

[tannewt]

This depends on esp32-camera support: espressif/esp32-camera#649

WIP commit to do this is here: tannewt@8a4ad54

Moving back to 9.x.x because it depends on espressif (hopefully) updating esp32-camera.

espressif/esp32-camera#677 which updates to the new I2C API, is now merged.
