This combines the two places where an error was generated for this into one and adds localiation for the message. The message is improved as requested in the bug.

The changes proposed here will speculatively parse all external scripts off thread as soon as they are fetched, except for async, link preload, and non parser inserted scripts. This should save us some time since currently all scripts are parsed right before execution or while they are blocking the dom parser.

The lack of specificity for script intro type has lead the debugger to need
to make use of 'source.introductionType' and 'source.element' in order to
determine whether a given script was injected, or inline or fetched, which
is entirely unnecessary of the loader itself clearly tells us what type
of script we are working with. It also allows us to cleanly handle the case
of XUL, which previously was "scriptElement" but has no ".element" passed
in, so we were unable to know whether a given source was inline or not.

There's no use case for stateful comparators, so they can be just plain
function pointers.
This is used in some hot places like CSS selector matching.

Doing this kind of censoring in "CreateScriptError" turns out to be more effort
than I thought. We don't have a JSContext to create Rooted instances.
This still catches all the relevant places where we are creating script-errors without inner-window-ids.

We can reduce the size of the SSO by removing the element slot entirely, and instead retrieve the element through a callback function. The callback will take in the value in the private slot of the SSO, which is either a LoadedScript* (from the browser) or a JSObject* (from the shell). In addition, this removes the requirement of having a script dom element ready when parsing a JS script which can open up new opportunities for performance.

and there is no fallback global available.
I assume there is little value in attempting to create another global if a
previous attempt failed.

To be able to remove SystemGroup, NS_ReleaseOnMainThreadSystemGroup
needs to have its dependency on SystemGroup removed. Since all
releases using SystemGroup would've released on the main thread anyway
we can safely replace NS_ReleaseOnMainThreadSystemGroup with
NS_ReleaseOnMainThread.

Rename ScriptLoader::mDocumentParsingDone to
ScriptLoader::mDeferCheckpointReached, and make it also get unblocked by
stylesheet loading.
Remove a useless null-check for mDocument as we unconditionally dereference it
below when checking mDocument->HaveFiredDOMTitleChange()
