feat: add support for ESP32-S3-WROOM-1-N16R8

Add support for ESP32-S3-WROOM-1-N16R8 module.

works for me.

Sorry for my ignorance, but why is the maximum_ram_size so large? Shoudn't it be just 512 KB? The other 8 MB aren't exatcly RAM, I guess, as it can't be used as stack memory, only as heap memory by calling ps_malloc().

There is already a file called 4d_systems_esp32s3_gen4_r8n16.json that seems to be very similar to the ESP32-S3-WROOM-1-N16R8 board, there the maximum_ram_size = 327680 (I believe some 192 KB are reserved to the system?).

Development version model: ESP32-S3-WROOM-1-N16R8, platformio.ini configuration is as follows:

[env:esp32s3]
platform = espressif32
board = esp32-s3-devkitc-1
framework = arduino
; 指定为16MB的FLASH分区表
board_build.arduino.partitions = default_16MB.csv
; 指定FLASH和PSRAM的运行模式
board_build.arduino.memory_type = qio_opi
; 预定义宏，启用PSRAM
build_flags = -DBOARD_HAS_PSRAM
; 指定FLASH容量为16MB
board_upload.flash_size = 16MB

Using this board file in my own projects let #include <Arduino.h> lead to this error:
framework-arduinoespressif32/cores/esp32/esp32-hal-gpio.h:29:10: fatal error: pins_arduino.h: No such file or directory.

If I replace the variant name esp32_s3_wroom_1_n16r8 by esp32s3, my projects compile!

Same behaviour here, trying to compile for Firebeetle2 N16R8; not sure if by setting it as esp32s3 we are "missing some cool optimization" or so

-DARDUINO_USB_CDC_ON_BOOT=1 probably shouldn't be enabled at this level, but in platformio.ini if it's needed.

I'm using this chip on an ESP32-S3-DevKitC-1. If this flag is included then I have to hold down the 'Boot' button and press 'Reset' every time I want to reflash. If this flag is removed then I can just 'Upload and Monitor' as normal.

-DARDUINO_USB_CDC_ON_BOOT=1 probably shouldn't be enabled at this level, but in platform.io if it's needed.

Same for -DARDUINO_USB_MODE=1 !

[chrBrd]

This section should include:

    "default_tool": "esp-builtin",
    "onboard_tools": [
      "esp-builtin"
    ],

to enable the built-in debugger.

[chrBrd]

This can safely be set to 921600 bauds.

All these changes look good and I can get programs to compile and upload with all of the suggestions. What's the hold up on getting it approved? Is it because @BA7LYA hasn't been active since July?

[sivar2311]

If this gets merged, what about all the other available ESP32-S3 configurations?

I would recommend using the default ESP32-S3 DevKit C and make the necessary modifications in platformio.ini.

Oh wow. @sivar2311 your documentation has improved even more since last I checked. You've got them all!! ...and I only have the N16R8 but that still looks incredibly useful... This seems like a very good solution for everyone...!
