Issue #2387 - Collection of fixes related to a crash while canceling a dynamic import. Add AddRef/Release hooks for embedding's script or module private value and set this script source object where appropriate. https://bugzilla.mozilla.org/show_bug.cgi?id=1519140 Partial, no Value passing changes. Clear the list of dynamic import requests after cancelling them in ScriptLoader::ParsingComplete as we do for other requests. https://bugzilla.mozilla.org/show_bug.cgi?id=1291535 ScriptLoader::OnStreamComplete never returns a failure. https://bugzilla.mozilla.org/show_bug.cgi?id=1627275 Also cancel the correct kind of parser for Modules.

Issue #2252 - Prevent crash when attempting to load a script with execution disallowed. This issue is due to the ExecutionContext added in Issue #1691 not handling GetScript() in a context where script execution is not allowed. This expressed itself in crashes when playing MP4s with the NoScript extension installed and enabled.

Issue #1691 - Part 12: Fix return value in ExecScript() and debug assert in ParseTask. https://bugzilla.mozilla.org/show_bug.cgi?id=1331662 Replace nsJSUtils::EvaluateString calls by ExecutionContext scopes. ExecutionContext: The mRetValue is not used even though it is checked in various asserts. This is how it is in the Mozilla code even years later, only the passed in value is used. ParseTask: JoinDecode() and JoinCompile() run the same code but the type is different causing a debug assert when it checks the type Script vs ScriptDecode.

Apparently Bing does rapid-fire loading/unloading of module scripts that causes
our attempts at resolving and initializing them to end up with null fetched

This commit does several things:
- Moves the pref check from ScriptLoader to ns[I]Document so it can be called on
the document.
- Changes the atrribute freezing function to a better name that takes the
document as a parameter.
- Sets the proper async/defer attributes on HTML script elements based on
keywords and whether they are module scripts or not.
