Add support for sunton esp32-2432s024{r,c}

[tinloaf]

This adds support for the Sunton esp32-2432s024{r,c} displays.

This is based on the code contributed by @elik754i in #555 . A few caveats:

• I do not own an esp32-2432s024r, only an esp32-2432s024c. So I cannot vouch that the "r" variant works. I have tested the "c" variant and it works.
• It looks like @elik745i added the support for the CST820 touch controller to an older version of the tft_driver_lovyangfx.cpp file than the version in the openHASP repo. I transplanted the necessary changes into the file in this repo. I do not know where they got that code from and I cannot read the chinese comments, but it seems to work.
• I am not sure about the naming. I think I read somewhere that the esp32 on these boards is an 'ESP32 S3', so I put the user-config into the esp32s3 folder, but I'm not sure what an 's2' or 's3' esp32 is or whether this is correct in this case.
• I'm not sure about the naming of the build environments. Some of the Sunton boards' environments seem to be named sunton-<whatever>, others just esp32-<whatever>. I opted for the latter, but feel free to change that.
