Use SVGLength-references in the SVGLengthContext API

Convert all the PassRefPtrWillBeRawPtr<SVGLength>-typed arguments to
const SVGLength&. This avoids unnecessary ref-count churn (the caller will
always own a reference anyway). As a side-effect footprint is reduced by
~2k. (resolveRectangle<T> can now be properly inlined and other methods
shrink a bit.)
