tools/intel_gpu_top: Add support of discrete GPU and card selection
In intel_gpu_top device path was hard coded for integrated GPU.
With this patch we:
* use igt_device_scan library for device scanning,
* make discrete GPU the default one,
* provided options for card selection.
v2:
* explicitly set ret to EXIT_SUCCESS after all the other uses
* fix use after free of opt_device (Tvrtko)
* use EXIT_FAILURE instead of "1" (Tvrtko)
