Add Espressif ESP32-S3-DevKitC-1-N16R8V board file

[handledexception]

Tested with PlatformIO 2.5.4 in VSCode with a TTGO T-Display-S3 16MB version.

Should resolve platformio#915

I can upload and debug my S3 dev kit module from here: https://vi.aliexpress.com/item/1005005045724400.html. Three problems remain: if I add debug_init_break = tbreak setup to the .ini file the debugger fails to start and without this command the debugger starts, but in an arbitrary place in the file C:\Users\Steven.platformio\packages\framework-arduinoespressif32\cores\esp32\main.cpp, which is not my source file, that is located at E:\Users\Steven\Documents\GitHub\PlatformIO\N16R8V\src\main.cpp. I can click continue and execution will stop in my code if I have set a breakpoint. Also the debugger always stops two lines after where the breakpoint is set. Have you seen or managed to overcome any of these issues?

Is this going to be merged?
