Add support for Brotli decompression 
For now, `BrotliDecode` hasn't been specified but it should be in a
close future.
So when it's possible we use the native `DecompressionStream` API
with "brotli" as argument.
If that fails or if we've to decompress in a sync context, we fallback
to `BrotliStream` which a pure js implementation (see README in external/brotli).

Hide the text in the text layer associated with MathML elements (bug 2009627) 
The bug was supposed to be fixed by #20471 but here there are some annotations in the pdf.
When those annotations are added to the DOM, the struct tree has to be rendered but without
the text layer (because of asynchronicity).
So this patch is making sure that the modifications in the text layer are done once the
layer is rendered.

Escape punctuation signs in search query 
It fixes #20516.

The chars `*{}()[]\` are punctuation signs in regex, so they need to be escaped
when searching for them literally.

bc87f4e8d6 Add the possibility to create a pdf from different ones (bug 1997379) 
For now it's just possible to create a single pdf in selecting some pages in different pdf sources.
The merge is for now pretty basic (it's why it's still a WIP) none of these data are merged for now:
 - the struct trees
 - the page labels
 - the outlines
 - named destinations
For there are 2 new ref tests where some new pdfs are created: one with some extracted pages and an other
one (encrypted) which is just rewritten.
The ref images are generated from the original pdfs in selecting the page we want and the new images are
taken from the generated pdfs.

8b17e5ecd8 Use canvas context text primitives when the font file is missing 
It fixes #20065.

The only to get a path (from the path generator) is when the font is embedded.
So when we need a path (disableFontFace: true or when we want to use a pattern for stroking/filling), it's impossible
to fulfil.
