Remove the unused getXhr-option in the NetworkManager constructor

Originally this file was shared, using pre-processor statements, between the generic PDF.js library and the built-in Firefox PDF Viewer. In the latter case the getXhr-option is being used, see https://searchfox.org/mozilla-central/rev/f32d5f3949a3f4f185122142b29f2e3ab776836e/toolkit/components/pdfjs/content/PdfStreamConverter.sys.mjs#612-621

Avoid some repeated stringToBytes-calls in the src/core/crypto.js file

Currently we repeatedly lookup, and convert to bytes, the "O" and "U" encryption-dictionary entries.

[api-minor] Stop including the "lib"-build in the pdfjs-dist repository

The pdfjs-dist/lib/ directory contains a README file that explicitly advises against using those files, however based on a fairly large number of issues filed over the years users seem to be (mostly) overlooking that warning.
In particular it unfortunately seems to be somewhat common for users to attempt to "combine" proper builds from pdfjs-dist/build/ together with individual components from the pdfjs-dist/lib/web/ directory, which more often than not leads to subtle bugs and general problems.

When we receive bug reports about this it's often not immediately obvious what the problem is, given that many issues lack enough details (such as runnable test-cases), but after some back-and-forth it usually turns out that usage of pdfjs-dist/lib/ is the culprit.
Considering that keeping the general PDF.js library working is challenging and time-consuming enough nowadays, this patch thus proposes that we stop including the "lib"-build in the pdfjs-dist repository to both reduce user confusion and the support burden.

Prevent incomplete copy-all behaviour while text-extraction is running (PR 16286 follow-up)

Currently we only prevent triggering the actual text-extraction multiple times in "parallel", when using the "copy all text" feature, however the "copy"-event itself is not prevented.
The result is that if the user selects all text in a long PDF document and then uses the copy-shortcut multiple times in quick succession, we'll actually populate the clipboard with "incomplete" contents (via a TextLayerBuilder copy-listener) until all text-extraction finishes.

All jobs completed, we found the following issues.

Lint Jobs Failed:

• source-test-mozlint-file-perm (cCAlsEoMRWOzhygu8hMglw)

Needs Investigation (Other Failed Jobs):

• source-test-mozlint-file-perm
  • 1 of 1 failed on the same (retriggered) task (cCAlsEoMRWOzhygu8hMglw)

These failures may mean that the library update succeeded; you'll need to review
them yourself and decide. If there are lint failures, you will need to fix them in
a follow-up patch. (Or ignore the patch I made, and recreate it yourself with
./mach vendor toolkit/components/pdfjs/moz.yaml.)

In either event, I have done all I can, so you will need to take it from here.
When reviewing, please note that this is external code, which needs a full and
careful inspection - not a rubberstamp.
