Add ESP32-S3 to ESP32 docker build

[duncandrennan]

• Added a docker image for building for ESP32-S3
• Current builds against v4.4.1 of the ESP-IDF which it fetches from https://github.com/duncandrennan/esp-idf.git using DOCKER_TAG=4.4-dev
• Has been tested to work building the bootloader (and can read/write flash with the bootloader stub)
• Work towards issue Support for ESP32-S3 #597

• Updated this to use Mongoose OS ESP-IDF
• Builds with DOCKER_TAG=4.4.1-r1

i think we can support all ESP32 devices (or all devices supported by ESP-IDF, really) with one image, we just need to include the toolchains

That makes sense. The only thing that I'm not sure about is how the environment variable MGOS_TARGET_GDB propagates through the mos system, as well as how rom.bin/elf are used. I see debug_core_dump.go (in mos tool) configures the platformDebugParams, so the rom files can be set that way. Looking further it looks like the MGOS_TARGET_GDB could also be shifted to the platformDebugParms and then appended in the same way as dp.extraServeCoreArgs.

Then each platform could have its own define, e.g. MGOS_TARGET_GDB_ESP32 (or ESP32S3, etc.).

I've updated this to build single ESP32 (ESP-IDF) docker image. I've left the existing defines/files (in particular rom.bin/elf and MGOS_TARGET_GDB) and added items for the -S3/C3. -S3 ROM is not yet available from the download link provided here, https://docs.espressif.com/projects/esp-idf/en/v4.4.1/esp32s3/api-guides/core_dump.html#rom-functions-in-backtraces.

Also updated the PR mongoose-os/mos#72
