Refactor fxjs_v8 and add embeddertests for it.
This forces the layer defined by fxjs_v8.h to be (more) self-contained, so that it can be tested apart from the CJS_* objects (in fpdfsdk/{src,include}/javascript. This implies the array buffer allocator must be part of fxjs_v8. One wrinkle is that we'd like to be able to test an isolate upon which no native objects have been added, so some initialization that would have occurred as part of object definition must be made explicit.
