Get the status of the display.

[dmazzella]

This functionality expose detect method for obtain the shield status.

Example usage:

void loop() {
  // Display
  if (!Display.detect()) {
    NVIC_SystemReset();
  }

  // LVGL
  lv_timer_handler();

  // IOT CLOUD
  do {
    ArduinoCloud.update();
  } while (block_for_ota);
}

in the production environment we have noticed the loss of connection to the display on the portenta h7 and this modification identifies this problem and allows an action to resolve the problem.

P.S.
the continuous call also unintentionally seems to have solved another vertical image scroll problem that often occurred when resetting the portenta via pin reset or via NVIC_SystemReset();

@leonardocavagnis please take a look at it and let me know.

Thanks for the PR!
I suggest renaming the API to detect() for better clarity
Also, please add the function to the API documentation

have you ever experienced this problem on portenta h7?

Nope, I haven't experienced it :( but I haven't tested it intensively. Thanks for pointing it out!

At the moment, I can't test the PR. If you confirm that the detect() function is working fine, I'll merge it. :)
Thanks!

I have tested this modification in production environment and work fine for me.
