Pass v8::Isolate to PDFium at init time.
Move the external isolate and embedder slot from the IPDF_JSPlatforms struct supplied at the FPDFDOC_InitFormFillEnvironment() call time to arguments to the FPDF_InitLibraryWithConfig() call. This has several benefits: -- Avoids the crash that could happen if multiple FPDFDOC_InitFormFillEnvironmen() calls should happen to be made by an embedder with different slot values. -- Down the road, for XFA, there may be XFA but no FormFill environment. We support both forms for the time being, until the chrome side catches up, at which point we will deprecate the old way.
