Should I add support to reduce code size when using LVGL?

[jadonmmiller]

I'm running into issues with the combination of LVGL/SPI_eSPi libraries being too big for my STM32 BluePill, and I was curious if the community and moderators would be interested in a pull request to reduce code size.

The proposed changes would:

• Use a #define statement in the user setup file to disable everything but the bare minimum required for LVGL.
• Preferably keep support for all display and platform types.

The code would still work exactly like before if you don't define the flag.

Please let me know if there's interest and feel free to ask questions or make suggestions!

On second thought: does the compiler even bother with functions that aren't used?
