libcamera: geometry: Clarify Rectangle's top-left corner
The libcamera::Rectangle class allows defining rectangles regardless of
the orientation of the reference system where a rectangle is used in.
This implies that, depending on the reference system in use, the
rectangle's top-left corner, as defined by libcamera, doesn't correspond
to the visual top-left position.

Clarify that a Rectangle's top-left corner corresponds to the point
with the smaller x and y coordinates and that the horizontal and
vertical dimensions are obtained by positive increments along the
corresponding axes.
