Simplify the PDFSidebar.#forceRendering method

The fallback code-path has never really been used, since the PDFSidebar is only used in the default viewer (and has never been exposed in e.g. the COMPONENTS-build).

Simplify the thumbnail styling in the viewer

This patch tries to simplify, and improve, the thumbnail styling:

• For rendered thumbnails there's one less DOM-element per thumbnail, which can't hurt in longer documents.
• Use CSS-variables to set the dimensions of all relevant DOM-elements at once.
• Simplify the visual styling of the thumbnails, e.g. remove the border since the viewer no longer has visible borders around pages, since the relevant CSS-rules are quite old code.
  These changes also, at least in my opinion, makes the relevant CSS-rules much easier to understand and work with.
• Make it easier to work on e.g. bug 1690428 without affecting the other sidebarViews.

Remove the unused isStandardFont font-property (PR 15880 follow-up)

This property was added in PR 12726 specifically for use in the getFontType function, indirectly used by the PDFDocumentProxy.stats getter in the API.
In PR 15880 that functionality was removed, but I forgot to remove this now unused font-property.

Remove SystemJS usage, in development mode, from the worker

Now that https://bugzilla.mozilla.org/show_bug.cgi?id=1247687 has landed in Firefox, we're able to use worker-modules during development :-)

This removes the final piece of SystemJS usage from the PDF.js library, thus allowing a fair bit of clean-up, and we now use only native import/export statements everywhere in development mode.

Inline the addPageIndex method in GlobalImageCache.shouldCache

When the GlobalImageCache implementation originally landed, back in PR 11912, the image handling was slightly more complex (with e.g. browser-decoding of some JPEG images). At this point it no longer seems necessary to manually handle pageIndexes in this way, and we should be able to simply inline that in the GlobalImageCache.shouldCache method.

Introduce a GitHub Actions workflow for publishing the website

This commit migrates this functionality away from the bots. Nowadays
it's possible to build and deploy the website to GitHub Pages directly
through the GitHub Actions, which provides a nice simplication of the
process. Not only does this remove the requirement to have a gh-pages
branch in the repository, it also avoids the complexity of having to
configure the workflow to commit to Git branches and allows us to remove
the Git committing code from the Gulpfile.

Note that deploying directly though GitHub Actions workflows needs to be
enabled in the repository settings, but this is easy and well documented
on the link below.

The following resources are relevant for this patch:

• Enabling deployment to GitHub Pages directly through GitHub Actions:

• Display the "notFound" message in bold.

Better approximate gradient color stops

PDF gradients do not have color stops but an arbitrary PDF function of
the type f(t) -> color. CSS gradients are only based on color stops.
Most PDF gradient functions are produced from color stop oriented
gradients.

Take advantage of this by sampling the PDF function at a higher
frequency but not converting any samples which could be interpolated to
color stops. The sampling frequency is chosen to be the least common
multiple of as many values as practical to exactly re-create the common
case of the PDF function implementing equally spaced linearly
interpolated stops in RGB color space. This also allows for better
approximation of other smooth PDF functions (non-linear, or non-equally
spaced, or in different color space).

I've submitted a try run for this commit: https://treeherder.mozilla.org/jobs?repo=try&revision=b957b9fd60475faae26d03ee0f8e59d3cd15aa6a

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.
