Generating the Kconfig file has to be done during preconfig otherwise anything kconfig related won't work. We can't source a file that doesn't exist yet. As it is now LVGL is downloaded during context (the usual), I think sourcing or just copying the Kconfig file from the LVGL folder would cause the configuration phase to fail, specifically the call to make olddefconfig.
