based on esp32s3-devkit:toywasm, tailored for the espressif fork
of qemu. [1]
* disabled a few things for which emulation doesn't seem available:
* wifi
* spiram
* ESP32S3_SYSTEM_BBPLL_RECALIB
* enabled DEBUG_SYMBOLS for my convenience (thus _debug suffix)
* enabled hostfs for my convenience
tested with:
qemu-xtensa-softmmu-esp_develop_9.0.0_20240606-x86_64-apple-darwin.tar.xz
