[Part 4] Parse the custom() function in -webkit-filter: parse the matN() functions
​https://bugs.webkit.org/show_bug.cgi?id=71444

Reviewed by Dean Jackson.

Source/WebCore:

Custom filter parameters should support mat2 to mat4 value functions. Added parsing
and style resolving bits to support the matrix function values. A later patch will
add the matrices to the shader program.
