Disable JavaScript entirely if no JSPlatform passed by embedder.
Allows run-time selection of whether to permit JS inside PDF. Previously,
this was a link-time decision only. This requires a little more caution
before we decide that we have the CJS_Runtime, and not the CJS_RuntimeStub
in a few casts.
Adds a kDisableJavaScript option to the form fill embeddertests.
Adds a --disable-javascript flag to the pdfium_test executable.
Also adds a --disable-xfa flag while we're at it.
