Move SVGTextMetricsBuilder metrics computation state to a local helper class
Move all transient state, and methods operating on it, from
SVGTextMetricsBuilder to a locally defined helper class
(SVGTextMetricsCalculator).
This leads to a structure that better represents the life-time of the
state, as well as reduce the size of SVGTextLayoutAttributesBuilder (and
hence indirectly RenderSVGText.)
