Reinhold Gschweicher 1b797211f1 main: fix segfault because of lv_task_handler() concurrently called 
Both InfiniSim/main.cpp and SystemTask.cpp periodically called
`lv_task_handler()`. This introduces a race condition, which leads to a
segmentation fault in either the main or the SystemTasks call of
`lv_task_handler()`.

Now `main` only calls the `lv_task_handler()` if the `SystemTask` does
not (while the screen is turned off). We need this for the Simulator,
otherwise the "Screen is OFF" message won't appear, and the right mouse
button won't be recognized to wake up the simulated screen.

Fixes: https://github.com/InfiniTimeOrg/InfiniSim/issues/3
