  [GPU Process][Filters] Make SVGFilter own a vector of unique FilterEffects
https://bugs.webkit.org/show_bug.cgi?id=256333
rdar://109060794

Reviewed by Simon Fraser.

Currently, SVGFilterExpressionTerm holds a Ref<FilterEffect> which may be referenced
more than once by multiple SVGFilterExpressionTerms.

We need make SVGFilter own a Vector of unique FilterEffects. SVGFilterExpressionTerm
will hold an index to this Vector. This will allow building an SVGFilterTransaction
which is a set of altered unique FilterEffects identified by the index in the vector
of unique FilterEffects of SVGFilter.
