Remove SVGTests related code from SVGGraphicsElement subclasses

Remove SVGTests related code from SVGGraphicsElement subclasses and it
add to the SVGGraphicsElement class instead. SVGGraphicsElement is the
one subclassing SVGTests after r153166.

Fixes for frame proxy to avoid double output in layout tests.

Calling out to m_baseProxy and the base object results right now in duplicate prints, since the base object also calls into WebTestProxyBase. I'm removing the extra calls right now and will add them as I migrate methods from RenderView to RenderFrame.

BUG=245126
