Eliminate SVGTextRunRenderingContext::m_activePaintingResource

Eliminate SVGTextRunRenderingContext::m_activePaintingResource

With geometry being emitted independently from the paint server setup, it
becomes possible to just rely on the current state of the GC when
painting SVG font text (which in turn allows us to make stricter
assumptions with more confidence elsewhere.)

Meddling with mostly disabled code is a bit scary, but...

Tested by enabling SVGFontsOnNonGDIPlatforms and (manually) running various
tests locally. (Like pservers-gradient-08.svg and all SVG-font-in-HTML tests I
could find.)

@fmalita: With this landed I think https://codereview.chromium.org/559653006/
should be a breeze =)
