In PR 19548 these checks were added to ensure that the font-data sent from the worker-thread *always* include correct `disableFontFace` and `fontExtraProperties` data.
For some reason PR 20197 then changed the code such that these checks became effectively pointless, since these properties are now checked after the fact *and* the new getters provide fallback values.
This method is only used with loops, and it should be a tiny bit more efficient to use an iterator directly rather than first iterating through the underlying data to create a temporary `Array` that we finally iterate through at the call-site.
*Please note:* As port of these changes the chars/glyph caches, on the `Font` instances, are changed to use `Map`s rather than Objects.

Using `0.0.0.0` instead of `localhost` allows connecting from other
devices, significantly simplifying testing on mobile devices.
This is controlled by the `--host` CLI flag and not enabled by
default, since allowing external connections comes with security
implications (e.g. when on a public network without a properly
configured firewall).
There might be reasons to want to listen on custom hostnames, but as
the most common usage will probably be `--host 0.0.0.0`, there is a
shorter alias `--host 0` for it.
Falling back to use the `loaded` byteLength if the server `contentLength` is unknown doesn't make a lot of sense, since it'd lead to the `onProgress` callback reporting `percent === 100` repeatedly while the document is loading despite that being obviously wrong.
Instead we'll now report `percent === NaN` in that case, thus showing the indeterminate progressBar, which seems more correct if the `contentLength` is unknown.
Please note that this code-path is normally not even reached, since streaming is enabled by default (applies e.g. to the Firefox PDF Viewer).
With these changes `0`, `NaN`, `null`, and `undefined` in the `total`-property all result in `percent === NaN` being reported by the callback, since previously e.g. `0` would result in `percent === 100` being reported unconditionally which doesn't make a lot of sense.
Also, remove the "indeterminate" loadingBar (in the viewer) if the `PDFDocumentLoadingTask` fails since there won't be any more data arriving and displaying the animation thus seems wrong.
This adds a basic non-MOZCENTRAL polyfill for now, which we should be able to remove once the next QuickJS version is released; note the pending changelog at f1139494d1/Changelog (L7)

This is not only shorter, but (in my opinion) it also simplifies the code.
*Note:* In order to keep the *five* different `BasePDFStreamReader` implementations consistent, we purposely don't re-factor the `PDFWorkerStreamReader` class to support `for await...of` iteration.
