anv/image: Enable specifying a surface's minimum pitch

This is required to create multiple, horizontally adjacent, max-width
images from one blit2d surface. This is also required for more accurate
width specification of surfaces within a larger surface (which is seen
as the smaller surface's enclosing region).

Note that anv_image_create_info::stride has been unused since commit,
b369389640 .
