window.postMessage uses lower priority queue during page load.
We should ensure the setup works also with Fission.

Ah, it added https://searchfox.org/mozilla-central/rev/3483fb259b4edbe4594cfcc3911db97d5441b67d/dom/base/TabGroup.cpp#258
and TabGroups are being replaced with BrowsingContextGroup.

Bug 1534012 added a test for postMessage during load and that revealed that mLoading flag isn't always updated
soon enough, so add BrowsingContext::IsLoading which checks also possible local loading status.

Depends on D54754
