Add a simple API unit-test for /BrotliDecode

This is a new feature in PDF documents, hence it shouldn't hurt to complement the existing ref-test with a simple unit-test as well.
This should also improve test coverage for the external/ folder, which can't hurt since the other external decoders are already fairly well covered.

fix: inline styles for hidden helper elements

Set layout-neutral styles at the creation sites for the hidden TextLayer
canvas and PDFViewer copy element rather than relying on the shared
web/pdf_viewer.css rule.

This keeps the helper elements invisible and out of layout when viewer CSS
selectors are scoped or omitted, and removes the obsolete hiddenCanvasElement
class and shared CSS rule.

Collect coverage information for the integration tests

Note that for the integration tests the coverage information ends up
being processed in the Node.js context where window is not available,
so we use globalThis instead for the function that merges individual
test's coverage information into the global object because that is
available in all contexts we support. For clarity we also rename said
function since we're not exclusively dealing with window nor worker
data anymore.

Avoid bundling DOM-related code in the built pdf.worker.mjs file

Currently the isCanvasFilterSupported/isAlphaColorInputSupported getters, on the FeatureTest class, contains code that cannot run in the worker-thread since it relies on the DOM being available.
To avoid that a new DEFINE is added, in gulpfile.mjs, to allow skipping this sort of dead code in the built pdf.worker.mjs file.

Remove the executable bit from test PDF files

Test PDF files should never be executable because we only read their
contents, so this commit makes sure that all test PDFs have the same
permissions, namely 0644 (read-only for all groups, and writable for the
owner), to limit their permissions for a least-privilege approach.

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.
