Are CSS_FILTERS always compiled in as well?

CSS_FILTERS are always compiled in as well. I'll be removing the CSS_FILTERS
flag next. 

CSS_SHADERS are a subset of CSS_FILTERS. This line is actually wrong in WebKit.
It should only check CSS_SHADERS because in WebKit, we assume if CSS_SHADERS are
on in a build, then CSS_FILTERS are on.
