Reduce duplication in the accumulateWheelTicks/accumulateTouchTicks methods (PR 15886 follow-up)

It just occurred to me that we can reduce some duplication by having the, virtually identical, accumulateWheelTicks/accumulateTouchTicks methods use a common helper instead that takes advantage of bracket notation.

Update the type/subtype at the end of font parsing

This fixes a warning reported by CodeQL, and should also make general sense given that we parse the font-data to determine the actual type/subtype rather than trusting the PDF document.

Validate the options before adding the ResizeObserver in the PDFViewer constructor (PR 15830 follow-up)

In the GENERIC viewer, it doesn't make sense to register the ResizeObserver if the container/viewer options are not valid.

Ensure that a document is loaded in PDFViewer.{increaseScale, decreaseScale} (PR 14053 follow-up)

This was always "wrong", since these methods (just like all the zoom-related ones) don't make sense unless there's an active document.

Enable the defaultZoomDelay option/preference unconditionally (PR 15812 follow-up)

This option/preference was disabled in GENERIC builds, see PR 15812, to avoid landing it just before a new release. Hence it should be fine to enable this now.

[api-minor] Limit the PDFDocumentLoadingTask.onUnsupportedFeature functionality to GENERIC builds (PR 15758 follow-up)

This was deprecated in PR 15758 but it's unfortunately quite difficult to tell if third-party users are depending on this, e.g. to implement custom error reporting, and if so to what extent.
However, thanks to the pre-processor we can limit most of this code to GENERIC builds which still seem like a worthwhile change.

These changes reduce the bundle size of the Firefox PDF Viewer by 3.8 kB in total.

[api-minor] Remove the PDFDocumentProxy.stats getter (PR 15758 follow-up)

This was deprecated in PR 15758 and given that it's quite unlikely that any third-party users are relying on this functionality, since it was only ever added to support telemetry reporting in the Firefox PDF Viewer, it should hopefully be fine to remove this fairly quickly.

These changes reduce the bundle size of the Firefox PDF Viewer by 4.5 kB in total.

[GeckoView] Remove the progressBar CSS variables, since they're unused

Given that there's no loadingBar element present in the GeckoView-viewer, we shouldn't need CSS variables for it.

Decouple the loadingBar background-color from the rest of the viewer

With upcoming background changes elsewhere in the viewer, this should be helpful in separating the styling of the loadingBar. These changes also means that both the "regular" and the "indeterminate" loadingBar now uses the same background-color value.

Also, shortens the related CSS variables a little bit since that can't hurt.

I've submitted a try run for this commit: https://treeherder.mozilla.org/jobs?repo=try&revision=bcf400b42537f2c96c801d1a3f1818a3d0143800

The try push is done, we found jobs with unclassified failures.

Needs Investigation (From Push Health):

No tests were found for flavor 'plain' and the following manifest filters:

skip_if, run_if, fail_if, subsuite(name=None), tags(['condprof']), pathprefix(['toolkit/components/pdfjs/test'])

Make sure the test paths (if any) are spelt correctly and the corresponding
--flavor and --subsuite are being used. See mach mochitest --help for a

These failures could mean that the library update changed something and caused
tests to fail. You'll need to review them yourself and decide where to go from here.

In either event, I have done all I can and you will need to take it from here. If you
don't want to land my patch, you can replicate it locally for editing with
./mach vendor toolkit/components/pdfjs/moz.yaml

When reviewing, please note that this is external code, which needs a full and
careful inspection - not a rubberstamp.
