Clarification OSAL Support (FreeRTOS, Windows, pthread ...) about lvgl HOT 5 CLOSED

Thank you for bringing this up. It really needs a better documentation. This page could be a good place for the additions.

Better documentation for what the LV_USE_OS flag is.

It enables the lv_mutex/thread/signal_*() functions. They are used during rendering to make LVGL yield the rendering task while it's waiting for a GPU or flushing. LV_USE_OS is also required for som GPU and for multi-core software rendering (each core has its own thread).

Does it make LVGL threadsafe?

No, it doesn't.

Do I need to call lv_task_handler?

Yes, you can do it anywhere and anyhow you want, but typically it's called in a task

If yes, do I need a mutex for it?

You need a mutex only if you call lv_* functions from an other thread too.

I now pointed out the issue on #5515, but I don't know if this is the right approach to fix it.

Probably I'm missing something but can't see how #5515 is related to this.
