Don't reset temporary XRef-entries during saving (PR 16392 follow-up)

Please note: I'm not aware of any bugs caused by this, however that might be more luck than anything else.

In PR 16392 the incrementalUpdate function, and all of its various helpers, were made asynchronous. However the call-site in src/core/worker.js wasn't updated, which means that we currently reset temporary XRef-entries while saving is ongoing.

Draw correctly background images in ref tests

Remove most build-time require-calls from the src/display/-folder

By leveraging import maps we can get rid of most of the remaining require-calls in the src/display/-folder, since we should strive to use modern import-statements wherever possible.
The only remaining cases are Node.js-specific dependencies, since those seem very difficult to convert unless we start producing a bundle specifically for Node.js environments.

[api-minor] Let Babel handle the necessary core-js polyfills automatically

In the last couple of years we've been quicker to remove support for older browsers/environments, which means that at this point in time we don't bundle that many polyfills. (The polyfills are also generally simpler nowadays, ever since we removed support for e.g. Internet Explorer.)
Rather than having to manually handle the polyfills, we can actually let Babel take care of bundling the necessary polyfills for us; please refer to https://babeljs.io/docs/babel-preset-env

The only exception here is the Node.js-specific compatibility-code, which is moved into the src/display/node_utils.js file. This ought to be fine since workers are not available/used in Node.js-environments.

Please note: For the legacy-builds this will increase the size of the built files, however that seems like a very small price to pay in order to simplify maintenance of the general PDF.js library.

[GeckoView] Fix l10n of the download toolbar-button (PR 16340 follow-up)

Localization of this button broke in PR 16340, which I assume was completely accidental, since the download-button now tries to access a l10n-id that was removed some time ago (see PR 15617).
Note how loading even the development viewer, i.e. http://localhost:8888/web/viewer-geckoview.html#locale=en-US, currently logs l10n-warnings on the master branch.

Remove the require from the web/pdfjs.js

Having a require in this file has never made sense in e.g. the Firefox PDF Viewer and shouldn't really be necessary.
Possibly the idea was to facilitate some kind of third-party bundling, however the built pdf.js file has always exposed the API-contents globally.

Re-factor the PDFScriptingManager-class for the viewer-components

Currently this class contains a few "special" code-paths for the COMPONENTS build-target, which normally wouldn't be a problem. However, in this particular case that means accessing code that we don't want to include unconditionally in all builds.
This is currently implemented using build-time require-calls which we nowadays want to avoid, and we should strive to remove all such cases from the code-base. (Generally speaking import is the future, and build-tools may not always play well with a mix of both formats.)

We can easily improve things here by using sub-classing for the COMPONENTS build-target, and then use the ability to re-name when exporting (to avoid breaking existing code).

Ensure that a test-suite that runs no tests is treated as a failure

Occasionally some test-suites may fail to start on the bots, however that's not correctly reflected in the botio-output posted to GitHub which makes it easy to accidentally overlook this situation.
Looking at the raw logs when that happens they always seem to contain a line such as Run NaN tests which means that we should be able to easily make this situation a failure as intended.

I've submitted a try run for this commit: https://treeherder.mozilla.org/jobs?repo=try&revision=31cc04f2240ab2c3e57f9f18bfbe8412c15e027c

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.
