Original change's description:
> [svg] Perform colorspace conversions for filter effects
> A filter effect can optionally be specified to operate in either sRGB
> or linearRGB, according to the SVG spec:
> This CL adds any necessary conversion steps (SkColorFilters) while
> constructing the filter DAG. The default filter effect color space is
> linearRGB. We should now be passing the filters-gauss-* W3C tests.
> Specific changes:
> - Tag filter effect results with their colorspace when storing them in
>   the filter context map
> - Add an SkColorFolor conversion step as necessary when resolving filter
>   effect inputs
> Bug: skia:10841
