`Blink.ino` does not compile for Nicla Sense ME, unless `#include "Nicla_System"`

Describe the problem

The Blink sketch does not run without modification on the Nicla Sense ME. It is required to add the #include "Nicla_System.h" directive, in order for the sketch to compile and successfully upload.

To reproduce

  1. Open Blink.ino from File -> Examples -> 01.Basics -> Blink.
  2. Connect the Nicla Sense ME board and select from the drop down menu
  3. Compile. A message informing the user to include the Nicla_System.h library is given in the bottom right corner

exit status 1

Compilation error: call to 'pinMode' declared with attribute error: Please include Nicla_System.h to use this pin
  1. Add #include "Nicla_System.h" just above the setup() function.
  2. Compile again, which will be successful.
Sketch uses 55788 bytes (10%) of program storage space. Maximum is 527616 bytes.
Global variables use 12256 bytes (19%) of dynamic memory, leaving 52032 bytes for local variables. Maximum is 64288 bytes.
  1. After uploading, all three RGB LEDs will start blinking together (white light)

Expected behavior

It is NOT required to add `#include "Nicla_System.h" to the sketch. Based on the selected FQBN, the compiler should add the directive if required.

Additional context

The Blink sketch is the de-facto Hello World example, and often the first sketch users upload to their board.
Replicated on IDE 1 and Web Editor also.

While there is a dedicated Blink_Nicla.ino sketch, the Blink.ino sketch should work with all boards.

The error directive was added to target EXACTLY that case; I think it's more than enough to drive the user to add the include (which is enough to make everything work automatically)
