According to the spec, requests created in HostLoadImportedModule have
the isTopLevel flag set to false. This means both static and dynamic
import requests should also have this flag set to false.

Step 4. Fetch a single module script given url, fetchClient, destination, options, settingsObject, referrer, moduleRequest, false, and onComplete.
The false argument in the second-to-last parameter of 'Fetch a single

CSS Modules are not supported in Workers and Worklets. This adds a
IsModuleTypeAllowed to ModuleLoaderBase so that the subclasses can
decide which modules are allowed.

There are shared path between "save bytecode" vs "cache stencil".
This patch just renames everything, and the subsequent bugs and patches will
split the flag and methods.

This already takes the referrer script. We can use the referrer script to keep
its private value alive in DynamicImportContextObject which is much simpler.

Previously we passed the module object for modules and nullptr for other cases.
This patch makes it so we pass the script for both module and classic script
referrers, and nullptr for the realm case.

Per the spec we should pass this to the module load hook. This means we can
remove JS::GetLoadingModuleHostDefinedValue.

This makes it the responsibility of the JS engine to deal with failure if the
module load hook fails. It's more convenient for the embedding to have this
handled for you.

This makes it so FinishLoadingImportedModuleFailedWithPendingException gets the
current exception and calls FinishLoadingImportedModuleFailed.
Differential Revision: https://phabricator.services.mozilla.com/D259612
We use ScopeExit here to ensure we call FinishLoadingImportedModuleFailed on
error. However sometimes we call this directly and then exit without releasing
the guard and so call it again.
The patch cleans this up and makes the guard report the pending exception if
set but still report an exception otherwise. (In future we might think about
insisting that an exception is set if we leave early.)

We usually use function pointers for callbacks into the JS engine.
These are simpler to deal with and also std::function can alocate memory in
some situations which is undesirable.
The patch converts these to function pointers and also refactors
ModuleLoaderBase.cpp where these are defined for the main module loader.

In mochitest-browser tests, it's possible for the about:neterror page to
load. This triggers aboutNetError.html, which in turn loads
aboutNetError.mjs, eventually importing pkijs.js. The pkijs.js module is
compiled off-thread.
However, when the test framework proceeds to the next test, the
associated document may be detached before the off-thread compilation of
pkijs.js completes. If this happens while TaskController is shutting
down, the compilation task may never finish.
Currently, ScriptLoader only tracks top-level off-thread compilation
requests, not submodules involved in those tasks. To address this, we
now call CancelFetchingModules when ScriptLoader cancels ongoing
requests, ensuring submodule fetches are also properly aborted.

When there's a ParseError, the error should be dispatched asynchronously.
However, workers can't handle the micro task, therefore we still call
ModuleErrored synchronously.
