M80: Avoid regenerating revision 5 and 6 encryption dictionaries.

Unlike revision 2 and 3, revision 5 and 6 encryption is not tied to the
document ID in the trailer. Thus regenerating the encryption dictionary
when the ID changes is completely unnecessary. Avoid doing this.

Unlike https://pdfium-review.googlesource.com/c/pdfium/+/63933, this
merge CL does not include the tests.
