Prior to this patch, PDF.js tracks both its own 'disabled' pref (which is used
by enterprise policy) and whether it is the default handler per the handler
service - but it tracks both in one bool, which determines whether its
streamconverter registers.
Really, what we want is to never use PDF.js if it's preffed off.
However, if there is some other default, it should be acceptable to use PDF.js
in some circumstances, like for <embed> or <object>s where otherwise we
would show no content at all.
Even for toplevel PDFs, if the user has configured Firefox to open PDFs in
an external helper app which is Firefox (which is currently an easy mistake
to make in the unknownContentType dialog), or has it set to the OS default,
but has changed their OS default to Firefox, we really still want to open
those PDFs with PDF.js.
This patch fixes all of this by splitting out the pref tracking from the
handler state tracking. Only the pref will completely disable PDF.js.
Then, in the streamconverter code, we check whether PDF.js should be used for
PDFs, and if there's a misconfiguration that we can correct. This code is
invoked from the parent process when we load PDFs in frames or toplevel
documents, and will prevent us from invoking PDF.js in the child if the user
would prefer that not to happen.
As a driveby, this cleans up how we track the pref inside PDF.js, and how we
get notified of changes to the handler - we were missing changes made in the
unknown content type dialog, so it seemed worth making it generic.

This also renames `saveToDisk` to the more accurate `promptForSaveDestination`
given that it doesn't actually do the saving itself.

Raw Cr.ERROR don't get stack information, same as throwing JS literals instead
of `new Error()`s.
This was done automatically with a new eslint rule that will be introduced in
the next commit. One instance of a raw Cr.ERROR was not replaced since it is
used in a test that specifically checks the preservation of raw Cr values in
XPCJS. The rule will be disabled for that instance.

There are many limitations currently, but this prototype should successfully
render most basic AVIF images. Known limitations:
- No support for any derived image items (crop, rotate, etc.)
- No support for alpha planes
- No support for ICC profiles (bug 1634741)
- The primary image item must be an av01 (no grid support)
- HDR images aren't tone-mapped

Also move MOZ_MUST_USE before function declarations' specifiers and return type. While clang and gcc's __attribute__((warn_unused_result)) can appear before, between, or after function specifiers and return types, the [[nodiscard]] attribute must precede the function specifiers.
I also needed to wrap the nsDocLoader::RemoveChildLoader() function declaration with // clang-format off and // clang-format on. clang-format insists on indenting the function declaration because it is confused by the NS_DECL_ macros without trailing semicolons before the [[nodiscard]] attribute.

Mostly a matter of:
rg -l '\->LoadingPrincipal' | xargs sed -i 's/->LoadingPrincipal/->GetLoadingPrincipal/g'
And then clang-format. But I tweaked manually nsHttpChannelAuthProvider (move
the variable where it's used, don't take a useless strong ref),
AddonContentPolicy (move the declaration of the variable to the if condition),
and BackgroundUtils (same).

This fixes 1597154 because the lists of URIs here and in nsDocShell now
match.
Note that they don't exactly match, there's an exception for about:newtab
which we'll fix in a follow-up bug.

It's only used to check whether the docshell is gone already, and we need to
deal with that in other places anyway. No other useful implementation.
In comm-central there are a couple, but they're useless too.
