Revert of Remove parameters which are always null (patchset #1 id:1 of https://codereview.chromium.org/2009413002/ )

Reason for revert:
Suspect that the lack of this parameter being
passed accurately to GetObject is leading to
https://bugs.chromium.org/p/chromium/issues/detail?id=613607, and that the right
fix will be to pass it.

Original issue's description:
> Remove parameters which are always null
>
> These parameters are never set, remove them and their supporting code.
>
> Committed: https://pdfium.googlesource.com/pdfium/+/818e1900a3811e1bde1e594e4966db612f845966
