[skif] Remove use of deprecated Magnifier factory within Skia
I deleted one old GM that didn't seem to be adding much value, and
adjusted the others to sort-of reconstruct the original lens bounds
and zoom amount. It's not perfect so I expect the gold images to
qualitatively change.
Updated the image filter fuzzer to use the new magnifier impl.
