[AE-432] Add Nicla Vision to build script

[aliphys]

This PR adds the Nicla Vision to the example build script:

• 🔍 The following three examples, common to all boards, are covered by the build script for Nicla Vision
  • examples/Battery
  • examples/Charger
  • ~examples/Standby_WakeFromPin~
• 📚 Currently, the Arduino_LowPowerNiclaVision library is not included in any of the examples nor source file. It is expected that this would change, given the compiler directives for the Nicla Vision e.g. https://github.com/arduino-libraries/Arduino_PowerManagement/blob/70b26666891fb0744a7dff2b922f871eb96d3f30/src/Board.cpp#L107-L119
• 🔑 A PAT is used to access the Low Power library for the Nicla Vision (see here).
