[Editor] Try to make the position of an edited FreeText the more accurated as possible

• Take into account the page translation,

Access the isOffscreenCanvasSupported option once in PDFViewerApplication._initializeViewerComponents

There's no good reason for getting this option multiple times in the same method. Also, we can slightly re-factor how the editorStampButton is made visible.

Tweak the writeStream implementation slightly

• Do the /Filter and /DecodeParms lookup in parallel, since that ought to be a tiny bit more efficient.
• Avoid code-duplication when CompressionStream isn't supported, since we already have a fallback code-path at the end of the function.

Re-enable editing, if necessary, when exiting PresentationMode (PR 16659 follow-up)

This regressed in PR 16659, when the signature of the PDFViewer.annotationEditorMode-setter was changed, and it currently leads to an Error being thrown when exiting PresentationMode.

[ESM] Convert the "default preferences"-handling to use import() syntax

Unfortunately I wasn't able to come up with a simple way to just replace the synchronous require-call, since we need to ensure that the default preferences are available when bundling starts.
Hence this patch adds a new intermediate parsing-step in all the relevant gulp-tasks, but this shouldn't affect build-times noticeable since the amount of extra parsing is very small.

Please note: It's very possible that there's a better way to handle this, however I figured that unblocking further ESM-work is more important than a "perfect" solution.

[CRX] Avoid encoding the fragment in file key

Semantically, it is more correct to encode the fragment in the URL
instead of the URL-encoded file query parameter. This shouldn't matter
in practice, because rewriteUrlClosure in chromecom.js decodes the
file parameter and restores the fragment. However, as #16625 shows,
there was a case where this did not work as expected.

[CRX] Re-initialize initialBookmark after URL rewrite

PDFViewerApplication reads from location.hash to initialize
initialBookmark. But when extensions/chromium/pdfHandler.js prepares
the redirect URL, the reference fragment is encoded instead of bare.
rewriteUrlClosure in chromecom.js is responsible for decoding the
URL, but that currently runs too late.

To fix this, update initialBookmark after rewriting the URL.

This was not a problem in the past because rewriteUrlClosure in
chromecom.js executed before the initialization of initialBookmark.
