esp32: Workaround IDF issue placing ISR ringbuf functions in IRAM.

Browse Source 
This workaround makes sure that all ringbuf functions that may be called
from an ISR are placed in IRAM.  See
https://github.com/espressif/esp-idf/issues/13378

Note that this means that all esp32-og builds get non-ISR ringbuf functions
placed in flash now, whereas previously it was just the spiram variant.
This might be a good thing (e.g. free up some IRAM for native/viper).

Fixes issue #14005.

This work was funded through GitHub Sponsors.
