While I wasn't able to figure out *exactly* why the old format didn't work, re-factoring the `parseOptions` function to use `yargs` differently "just worked" so that's hopefully good enough here.
With these changes everything related to a *particular* option now appears in one place, rather than being spread out, which aids readability in my opinion. Also, the options are now sorted alphabetically, to make it easier to find a particular one.

According to a decision by UX and PM, please see https://bugzilla.mozilla.org/show_bug.cgi?id=1705060#c2 (and implemented in https://bugzilla.mozilla.org/show_bug.cgi?id=1705327), we no longer show the notification-bar in Firefox; hence the special `PDFViewerApplication._delayedFallback` functionality should no longer be necessary.
Furthermore, note that at this point in time *most* of the features which used the `PDFViewerApplication._delayedFallback` functionality is now enabled by default; hence that provides even less reason to keep this code around and existing calls are thus converted to "regular" `PDFViewerApplication.fallback` calls.
According to a decision by UX and PM, please see https://bugzilla.mozilla.org/show_bug.cgi?id=1705060#c2, in Firefox we should first of all *not* display the notification-bar for signatures. Secondly, as can also be seen there, we shouldn't display the notification-bar *at all* and it's thus disabled in https://bugzilla.mozilla.org/show_bug.cgi?id=1705327.
If we purposely don't display a notification, for documents with signatures, in the *built in* Firefox PDF Viewer then it cannot be necessary in the GENERIC viewer either.
- Different fonts can be used in xfa and some of them are embedded in the pdf.
- Load all the fonts in window.document.

There is no asynchronous code involved here, so we can get rid of all
done callbacks here and simply use the fact that if the function call
ends without failed assertion that the test passed.

I've successfully run `gulp mozcentral` and `gulp generic` locally, with/without this patch and diff-ed the *built* `web/viewer.css` files. There were no changes, in the build-output, caused by this update.

`setSelectionRange(0, 0)` added in 44b24fcc29 for #12359, required only by Firefox ([bug](https://bugzilla.mozilla.org/show_bug.cgi?id=860329)), causes issues mozilla#13191, mozilla#12592 in Safari.
`scrollLeft = 0` is a fix that breaks the focus trap in Safari while **keeping Firefox behavior same for #12359**.
Remove the unused "GetIsPureXfa" message handler; and avoid unnecessary parsing when no structTree is available (PR 13069 follow-up, PR 13221 follow-up)
With the current implementation of `PDFDocument.hasJSActions`, in the worker-thread, we're not actually handling not-yet-loaded data correctly. This can thus fail in *two* different ways:
- The `PDFDocument.fieldObjects` getter (and its helper method), while it may *return* a Promise, still fetches all of its data synchronously and it can thus throw a `MissingDataException` during parsing.
- The `Catalog.jsActions` getter, which is completely synchronous, can obviously throw a `MissingDataException` during parsing.
If either of these cases occur currently, the `PDFDocumentProxy.hasJSActions` method in the API can either return a *rejected* Promise (which it never should) or possibly "hang" and never resolve.
*Please note:* While I've not *yet* seen this error in an actual PDF document, it can happen during loading if you're unlucky enough with e.g. the structure of the PDF document and/or the download speed offered by the server.
This patch is thus based on code-inspection *and* on manually throwing a `MissingDataException` on the first access of `Catalog.jsActions` to simulate this situation.
Finally, this patch adds a couple of *API* unit-tests for this (since none existed).
Given that this only an internal helper method, used by the `Catalog.{javaScript, jsActions}` getters, this change simplifies iteration of the returned data.
We can also (slightly) re-factor the code of the `jsActions` getter, and remove an obsolete[1] JSDoc-comment from the `openAction` getter.

[1] Not really relevant now that we've got proper scripting support.
Similar to all other data accesses, note e.g. the "GetDocJSActions" handler just above, we need to ensure that a `MissingDataException` isn't propagated to the main-thread if this data is accessed while the PDF document is still loading.
