Improve the StructTreeLayerBuilder.render method

In hindsight it occurred to me that there's a couple of smaller issues with this method after it's made asynchronous (in PR 18658).

• If the render-method is invoked back-to-back the existing caching doesn't guarantee that re-parsing won't occur, which we can address by introducing a new (private) promise.

• If there's any errors fetching and/or parsing the structTree-data, we'd attempt to parse it again on re-rendering despite that being pointless.

It has been tested with Voice Over (mac) and with NVDA (windows).

When an added stamp annotation is focused, the screen reader will announce
that it's a figure containing a graphic with the added alt-text.

Use Headers consistently in the different IPDFStream implementations

The Headers functionality is now available in all browsers/environments that we support, which allows us to consolidate and simplify how the httpHeaders API-option is handled; see https://developer.mozilla.org/en-US/docs/Web/API/Headers#browser_compatibility

Also, simplifies the old NetworkManager-constructor a little bit.

Use "full" localization ids in the PDFDocumentProperties class

It was recently brought to my attention that using partial or generated localization ids is bad for maintainability, which means that PR 18636 wasn't the correct thing to do.
However, just reverting that one doesn't really fix the problems which is why this patch updates every l10n-id in the PDFDocumentProperties class (but doesn't touch any viewer.ftl-files). Obviously this leads to more verbose code, but that cannot really be helped.

Simplify the PDFDocumentProperties.#updateUI method

We can remove the reset-parameter, since it's redundant, given that it's only used after PDFDocumentProperties.#reset has been invoked which means that this.#fieldData === null which is equivalent to resetting.
Also, we don't need to have two separate loops in order to update the UI in this method.

Finally, inline the DEFAULT_FIELD_CONTENT constant now that it's only used once.

Use the URL global instead of the deprecated url.parse

The Node.js url.parse API (https://nodejs.org/api/url.html#urlparseurlstring-parsequerystring-slashesdenotehost)
is deprecated because it's prone to security issues (to the point that Node.js doesn't even publish CVEs for it anymore).

The official reccomendation is to instead use the global URL constructor, available both in Node.js and in browsers.
Node.js filesystem APIs accept URL objects as parameter, so this also avoids a few URL->filepath conversions.

[CRX] Remove obsolete manifest features

In preparation for migrating the Chrome extension to Manifest Version 3,
this patch removes parts of the manifest that are obsolete and/or
unsupported in MV3.

Remove ftp mentions: ftp was dropped from 6 years ago, in Chrome 59.

Remove file_browser_handlers: does not work on Chrome OS according to
https://github.com/mozilla/pdf.js/issues/14161 . MV3 replacement needs
a different manifest key and logic, which will be added later.

Remove content_security_policy: MV3 does not support unsafe-eval CSP,
and PDF.js does not require it. This may result in a mild performance
degradation in PDFs that contain PostScript.

Remove page_action logic: When this logic was originally introduced,
Chrome showed page action buttons in the address bar, which enabled
the extension to display the button on specific PDF viewer tabs only.
In Chrome 49 (2016), pageActions were dropped from the address bar and
put in an UI area that is hidden by default. The user can pin the button
to be unconditionally visible on the toolbar, which is distracting.
Because the UX is no longer serving the original needs, this patch
removes page_action from the manifest.

Upgrade Puppeteer to version 23.1.1

This major version contains three breaking changes that impact us:

• The product option has been renamed to the more suitable browser.
• The page.screenshot() API returns a Uint8Array instead of a
  Buffer, but since pngjs requires a Buffer object we need to do
  the conversion using Buffer.from() before passing data to pngjs.
• The browser configuration should be set using a configuration file
  instead of environment variables. Note that as a bonus this allows us
  to remove the cross-env dependency since that was only used to set
  the Puppeteer environment variable equally for all operating systems.

For more information about the changes between the old and new Puppeteer
versions refer to https://github.com/puppeteer/puppeteer/releases.
