libcamera: geometry: Use Size to store min and max in SizeRange
Instead of storing four integers for the minimum and maximum width and height in the SizeRange class, use two instance of the Size class for the minimum and maximum sizes. While it at replace the mention of image size with size in the SizeRange documentation, as the Size class isn't limited to image sizes.
