NOTE: I sent this CL out for review once before, but accidentally deleted it
before it got reviewed.

===

Rollback part of CL 6139360. That change implemented ModuleWrapper and
JsCallContext for IE and made the GearsTest module use it.

The implementation of ModuleWrapper is incomplete though and getting in the
way of people using GearsTest for other things.

This change leaves ModuleWrapper and JsCallContext checked in, but not
hooked up to anything. It also reverts GearsTest to use COM and XPCOM.
