lvgl/Makefile: support multiple options for LV_OPTLEVEL

This configuration is added to put LVGL into PSRAM for execution, and the lv_*.o file needs to be matched in the link script. Since LTO optimization will cause the file name to be modified, resulting in a matching failure, it will only take effect if LTO optimization is removed during compilation.
