SVGPathUtilities tidying

Rename buildSVGPathByteStreamFromString to buildByteStreamFromString to
be more consistent with other functions (buildStringFromByteStream and
buildPathFromByteStream). Also drop the PathParsingMode argument, since
it's always UnalteredParsing (and it's unlikely we'll need to build
normalized byte streams ATM.)

Make buildStringFromByteStream return the resulting String instead of
using an out-parameter. Tidies up call-sites and makes for slightly
smaller code.
