libcamera: geometry: Add comparison operators to geometry classes
Add equality and inequality comparison operators for the Rectangle, Size and SizeRange classes. For the Size class, also add ordering operators. Sizes are first compared on combined width and height, then on area, and finally on width only to achieve a stable ordering.
