Remove kernelUnitLength plumbing

'kernelUnitLength' is not supported in Blink, and is deprecated in the
spec [1][2][3].
Rip out the plumbing and (FilterEffect) storage for it, since it's dead
code for practical purposes (see below though...)

The svg/dynamic-updates/SVGFEConvolveMatrixElement-*-kernelUnitLength-*
tests now actually show something because the kernelUnitLength of 0.05
no longer truncate to 0 and trigger an error. (0.05 should have been a
valid value previously too.)

The tests for negative kernelUnitLengths are dropped because they're no
longer of any use.

    (feSpecularLighting seems to be missing the Note, but it's the same
     as for feDiffuseLighting anyhow.)
