Move the fixupLangCode helper function into the web/genericl10n.js file

This helper function was added almost two years ago, in PR 13696, and it still has only a single call-site. Furthermore, with the changes made in PR 16572 it also cannot hurt to reduce the size of the web/l10n_utils.js file slightly.

[Firefox] Avoid unnecessary string-parsing when reading preferences

Note how the ChromeActions.getPreferences method returns the preferences as a string, which we then have to convert back into an Object in the viewer.
Back when that code was originally written it wasn't possible to send Objects from the platform-code, however that's no longer the case and we should be able to (eventually) remove this unnecessary string-parsing now.

Please note that in order to prevent breakage we'll need to land these changes in stages:

• Land this patch in mozilla-central, as part of regular the PDF.js updates.
• Change the return type in the ChromeActions.getPreferences method, in a mozilla-central patch.
• Remove the string-handling from the FirefoxPreferences._readFromStorage method.

[Firefox] Disable the ability to change preferences directly from the viewer

Please note that we've never had any functionality in the viewer itself that set preferences, and we've thus only ever read them.
For the GENERIC viewer it obviously makes sense for the user to be able to modify preferences, e.g. via the console, but that doesn't really apply to the built-in Firefox PDF Viewer since preferences are already accessible via about:config there. Hence it does seems somewhat strange to expose, a limited part of, the Firefox preference system in this way when we're not even using it.

Note that the unused preference setting-code also include a fair amount of additional validation on the platform-side, such as limiting any possible preference changes to the pdfjs.-branch and also an explicit white-list of preference names[1], to make sure that this is safe; please see:

• https://searchfox.org/mozilla-central/rev/4e8f62a231e71dc53eb50b6d74afca21d6b254e9/toolkit/components/pdfjs/content/PdfStreamConverter.sys.mjs#458-495

Assuming that this patch lands, I'll follow-up with a mozilla-central patch to remove the code mentioned above.

[1] This hard-coded list contains preferences that no longer exist, and also at least one (fairly obvious) typo.

Remove the OverlayManager.unregister method since it's completely unused

This method was added only for consistency with the register-method, however it's never actually been used. To avoid including dead code in the builds, let's just remove the unregister-method for now.

Please note: If this method ever becomes useful, it'll be trivial to revert this commit.

[api-minor] Move the l10n-translation into the AnnotationLayer

[api-minor] Ensure that the AnnotationLayer gets a default l10n-instance in GENERIC builds (PR 16552 follow-up)

This is something that I completely overlooked during review of PR 16552, despite leaving a l10n-related comment.

The new l10n-handling of PopupAnnotations assume that the AnnotationLayer is always initialized with a l10n-instance, which might not actually be the case in third-party implementations where the default viewer isn't used.
To work-around that we'll now bundle, and fallback on, the existing NullL10n-implementation in GENERIC builds of the PDF.js library. This will only result in a slight file-size increase for the built pdf.js file, again limited to GENERIC builds, since the web/l10n_utils.js file has no dependencies.

Also, tweaks a couple of TESTING pre-processor checks to only include that code when running the reference tests.

[api-minor] Make the popup independent of their associated annotations

• it'll help to be able to move popups on screen to let the user read the text
• popups won't inherit some properties from their parent:
  • the popup can be misrendered if for example the parent has a clip-path property.
• add an outline to the popup when the parent is focused.
• hide a popup when it's clicked.

All the jobs in the try run succeeded. Like literally all of them, there weren't
even any intermittents. That is pretty surprising to me, so maybe you should double
check to make sure I didn't misinterpret things and that the correct tests ran...

Anyway, I've done all I can, so I'm passing to you to review and land the patch.
When reviewing, please note that this is external code, which needs a full and
careful inspection - not a rubberstamp.
