There are a few places where we call one of two overloads of a fuction based on
the contents of a MaybeOneOf. We can simplify this code by giving the class a
map method.

This removes the global object field from the script load context and gets the
global from the script loader / module loader where necessary.
Differential Revision: https://phabricator.services.mozilla.com/D142833
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.

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.

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.

To add conditional JS::StartIncrementalEncoding, and also to add a bytecode
decoding branch, replace nsJSUtils::CompileModule with raw JSAPI calls with
Stencil.

As a preparation to add bytecode case to CompileOrFinishModuleScript, removed
the shared nsresult variable and make each branch directly return, and also
do early return for error case.

The crashes were occurring due to the missing webext global on dynamically imported modules from a referencing script. There is likely a more elegant way to reintroduce this, but for now this is a quick fix.
