[CI Filters] Implement all the FEColorMatrix options in Core Image
https://bugs.webkit.org/show_bug.cgi?id=304890
rdar://167484500
Reviewed by Mike Wyrzykowski.
Add support for the `luminanceToAlpha` type of FEColorMatrix, by defining a
function
in ColorMatrix.h to return the relevant matrix. The coefficients are from the
spec,
but slightly different from what we use in `FEColorMatrixSoftwareApplier` for
unknown reasons. Also clamp the output from the color matrix filter.
