Changing XPathGrammer.y to not use global using blink

Changing XPathGrammer.y to not use global using blink

When using "using namespace Foo" at global level you will
introduce a lot of symbols into the global scope which will make
it harder for jumbo (unity builds/merged files) to compile without
symbol collisions.

Also, global using namespace statements will, with the current
implementation of jumbo not compile because of a compiler warning.

This patch changes to more explicit namespaces.
