Introduce kPerIsolateDataIndex and tidy JS_Define.h
Follow-up from https://codereview.chromium.org/1366053003/ - use kPerIsolateDataIndex rather than magic constant 1. - make a helper function for common code in JS_Define.h - remove dead prototypes missed in earlier CL. - fxjs_v8 can't include generic fpdfsdk includes (layering). R=jochen@chromium.org Review URL: https://codereview.chromium.org/1367813003 .
