* Native: Libgpiod: Add GetNumberOfChips method

Some SoCs have more than one GPIO bank. For these we gave more than one entry in /dev/:
/dev/gpiochip0, /dev/gpiochip1 ... /dev/gpiochipX

This patch add a method to return how many GPIO banks the hardware have.

* System.Device.Gpio: GpioController: Add SetDefaultGpioChip

Some SoCs have more than one GPIO bank. For these we gave more than one entry in /dev/:
/dev/gpiochip0, /dev/gpiochip1 ... /dev/gpiochipX

This patch add a method to select the default GPIO bank to be used on the GpioController.
If the hardware has only one GPIO bank (/dev/gpiochip0 like the rpi) it will be automatically set in
the GpioController constructor. But if the hardware has more than one GPIO bank the bank to be used
for GpioController operations should be defined.

Ex: Access GPIO bank 3 (/dev/gpiochip3) line 17:

GpioController gpioCtrl = new GpioController();
gpioCtrl.SetDefaultGpioChip(3);
gpioCtrl.OpenPin(17, PinMode.Output);
