Tests have shown that web pages use base64url encoded integrity
metadata when using SRI, as other browsers are already supporting it.
To align cross-browser behavior, we'll support base64url and base64
in parallel and update the tests from wpt at the same time.

Cancellation happend in ParsingComplete() and Destroy() but was inconsistent in
which kinds of requests were cancelled and which were cancelled and removed.
This makes one method that cancels and removes everything and uses it in both
places.

This just moves the method definitions so that they appear in roughly in the
order they are executed, to make reading and understanding this easier.

This renames the following in an attempt to give consistent names to off-thread
compliation related things:
- AttemptAsyncScriptCompile -> AttemptOffThreadScriptCompile
- NotifyOffThreadScriptLoadCompletedRunnable -> OffThreadJobCompleteRunnable
- OffThreadScriptLoaderCallback -> OffThreadJobCompleteCallback

The main change in this patch is to prevent access to main-thread objects
while off-thread. This is done by using nsMainThreadPtrHandle to wrap main
thread pointers in the runnable. This prevents access to their targets when
off thread and ensure they are only released on the main thread.
This means that mRunnable is now only accessed on the main thread and so it
doesn't need to be atomic and can be a normal RefPtr. We also don't need to
leak a reference to it in AttemptOffThreadScriptCompile.
This also requires that timing data is moved to the runnable.
Cancellation should always have happened by unlink or destruction of
ScriptLoadContext so handling for that is removed.

Note that modules can't be specified in Link preloads with `rel=preload`,
only in `rel=modulepreload`. We currently only support `rel=preload` in
early hints. See Bug 1798319 for updates on module preloads.

The problem is that synchronous XMLHttpRequest requests can spin the event loop
and cause us to process dynamic module loads (by calling
JS::FinishDynamicModuleImport) when we are already inside JS::ModuleEvaluate.
The module algorithms assume that they are not reentrant.
The patch changes dyammic module load processing to happen in the same way as
async script loads (of both classic scripts and modules), which are blocked
during sync XHR by Document::SuppressEventHandling calling
ScriptLoader::AddExecuteBlocker.
