esp32/machine_sdcard: Add SDCard pin assignments for ESP32-S3 support.

Browse Source 
Previously ESP32-S3 SDMMC could only use fixed pin assignments, however the
ESP-IDF defaults don't match common boards. The chip also supports using
GPIO Matrix to assign any pin.

This work was funded through GitHub Sponsors.
