default globals implementation

RFC: emberjs/rfcs#1070

This looks like a good start covering the ECMA globals. Perhaps we also care about some WHATWG globals:

https://html.spec.whatwg.org/multipage/nav-history-apis.html#window

I think it's fine to be choosy, there is definitely stuff in there that is pretty much legacy (like name) that is probably just a troll. But other things seems likely to be useful and people will try to use them (focus? blur? postMessage?).

[NullVoxPopuli]

oooo, ya good thinking. doing (fn postMessage ...) would make for some fun demos

[NullVoxPopuli]

done!

@NullVoxPopuli @ef4 any feeling on what the impact of this change is? it feels like it's kinda breaking but not really in a way that should be exposed to the end user 🤔

[NullVoxPopuli]

it's 100% non-breaking, because if you tried to use a global before this PR, you'd just have an error.

[ef4]

Correct, it's not breaking.
