Summary:
Adds pros::lcd::is_initialized to the weak symbol table for LLEMU stubs. This is a way to help templates who check for this (such as EZTemplate) to see if both LVGL is installed and LLEMU is initialized. To accomplish this, this function will return false if it is still defined as the weak symbol.
