This introduces the basic skeleton to make WorkerScriptLoader a ScriptLoaderInterface.
ScriptLoaderInterface defines the methods that are shared between any given ScriptLoader (for
example the DOM script loader, the ComponentScriptLoader) and the ModuleLoader for a particular
component.
This patch also adds documentation to make the role and responsibilities of the
ScriptLoaderInterface clear.

Since mozJSComponentLoader is destroyed after the cycle collector, we need to
break cycles manually before the final cycle collection otherwise we get a
memory leak. Unload() is called at an appropriate earlier point in shutdown.

This adds the parameter to the module loaders evaluation method. I also
rewrote the comments a bit to make this section clearer based on my
understanding of how this works.

The main version of EvaluateModule will continue to use AutoEntryScript, but we
don't always want it's error reporting behaviour.

Module loaders require an event target to use with mozPromise. The default uses
the event loop so doesn't permit implementing a synchronous module loader.

Classes with virtual methods should have a virtual destructor so deleting an
object through a base class pointer works correctly. I think I got lint
warnings about this when I added a new derived loader.

Give the caching interfaces default empty implementations so derived classes
don't need to implement them if they don't want any speical behaviour. We don't
use these methods for caching in mozJSComponentLoader.

Module imports can be cyclic so it's more correct to refer to them as graphs.
The spec also uses this term.

This renames the method to correspond to StartFetch and adds a status argument
so clients can call this rather than
SetModuleFetchFinishedAndResumeWaitingRequests on error.

This gives the module loader a field for the current global, since a module map
is only associated with a single global.
This adds a method to Document to tell the script loader when its global
changes. I'm not sure of when we do this exactly.

The script loader will need to deal with requests from more than one module
loader so this adds methods to the request which dispatch to the correct
loader.

StartModuleLoadImpl moves to the base class and uses to new virtual methods
CanStartLoad and StartFetch which are implemented by the derived class.

Now we can move the JS engine integration hooks into the generic module loader.
There is still some code there to deal with web extension globals. This will be
removed in a later patch.

This adds a new virtual to the module loader base, along the same lines as the
one to create a load request for a static import. This makes the
HostImportModuleDynamically hook generic.

This adds a virtual method to nsIGlobalObject and implements it for
nsGlobalWindowInner and SandboxPrivate. This means we don't have to put the
logic for dealing with all the different kinds of globals in once place.

This splits the interface of ModuleLoaderBase into sections and restricts acess
for internal methods.

After enabling bytecode cache for module script, we need to handle
the SRI mismatch on bytecode cache, that requires reloading the script source
again.
Differential Revision: https://phabricator.services.mozilla.com/D140551
The module scripts are scanned immediately before executing, and if the
module script is not yet executed, and it matches the requirement for encoding
(size, fetch count, etc), it's marked as encode,
and they're scanned again immediately after executing, and marked scripts are
queued for bytecode encoding.
This patch doesn't actually enable the encoding, given ShouldCacheBytecode
returns false because the caching is not enabled for the channel and
GetCacheTokenFetchCount fails.
