    js: Replace JSRuntime APIs that now take JSContext
    
    Many APIs that adapted to the removal of JSRuntime can be trivially
    replaced with JSContext without any other code changes.
    
    JS_AbortIfWrongThread() also takes JSContext instead of JSRuntime, but
    we only called it to check that we were creating a JSContext on the
    correct thread. Before creating the JSContext, there is no point in
    calling it, so remove it.
