Fix regions on F746ZG (#391)

[piwi1263]

• Block regions corrected
• Memory regions corrected

Set GPIO API to true in cmake-variants, build in VS Code.
Performed a full erase and deploy of generated hex binaries.
Connected an external LED on PC10 to have a small VS17 solution make a blinky.

Although trivial but for completeness:

using System.Threading;
using Windows.Devices.Gpio;

namespace NFApp2
{
	public class Program
    {
        // For F4-Discovery -> Off board LED is on PB7 = 1 * 16 + 7 = 23 
        // For F769I-DISCO -> LED2_GREEN is on PJ5 = 9 * 16 + 5 = 149
        // For F746ZG-NUCLEO -> Off board LED is on PC10 = 2 * 16 + 10 = 42 
        private const int LED_PIN = 42;
        private const string NAME = "Chewbacca";

        // Set up the LED
        private static GpioPin LED;

        public static void Main()
        {
            var gpio = GpioController.GetDefault();
            LED = gpio.OpenPin(LED_PIN);
            LED.SetDriveMode(GpioPinDriveMode.Output);

            for (;;)
            {
                LED.Write(GpioPinValue.High);
                Thread.Sleep(100);
                LED.Write(GpioPinValue.Low);
                Thread.Sleep(100);
            }
        }
    }
}
