Daniel Holbert 76a8cb61f7 Bug 1516025 part 2: Add needed #includes to some files in dom/svg to preemptively fix unified build bustage. r=longsonr
And while I'm here, I'm giving SVGDataParser.h a more specific/efficient string
include, to just provide the *forward-decl* of nsAString for this file's
"nsAString&" usage in a function prototype.

Depends on D15231
