Implement a generic matrix transform image filter.

This will be used in Blink to accommodate matrices that contain
rotation or shearing. This is a generalization of SkResizeImageFilter,
so I've replaced all uses of SkResizeImageFilter in Skia. (It might be
easier to review by diffing it with SkResizeImageFilter, too.)
