Bug 1516025 part 1: Add "using namespace mozilla::dom" to some SVG C++ files that currently depend on unification to provide that using statement. r=longsonr

These are to support of usages of "SVGElement" in these files, so they
problably only started needing this namespace as of bug 1515187.  In any case,
they're currently relying on picking up this "using" statement from other files
in unified builds, so let's just make the usage explicit by giving them their
own "using" statement.

Also, I'm fixing up the #include for SVGElement.h in these files to use the
full mozilla/dom include path (and to make these files include their own .h
file first).
