Segv when PDF-side JS object property getter invoked from XFA.
The PDF-side native objects require that the current v8 context has been set-up to point at the state (via CJS_Runtime) for the getters, setters, and methods to operate against. XFA doesn't supply a context with that state, so at the first opportunity for a PDF-side object to be leaked to XFA, set up the context to mimic the PDF side. Changed FXJS_GetRuntimeFromIsolate() to FXJS_GetRuntimeFromV8Context() for consistency with the newly added method. BUG=pdfium:266 R=jochen@chromium.org Review URL: https://codereview.chromium.org/1412103010 .
