Place non-ISR ringbuf functions (like xRingbufferCreate/xRingbufferSend) into flash.
This frees up IRAM, but the functions can no longer be called when the cache is disabled.

esp_ringbuf: Added functions to linker.lf file which can be placed in Flash This commit adds symbols from the ringbuf.c file which can be placed in Flash in order to free up IRAM space.

This frees up IRAM, but the functions can no longer be called when the cache is disabled
or from an IRAM interrupt context.

This option is not compatible with ESP-IDF drivers which are configured to
run the ISR from an IRAM context, e.g. CONFIG_UART_ISR_IN_IRAM.
