WindowOrWorkerGlobalScope should extend GlobalFetch

[ghost]

Since it redeclares fetch(input: RequestInfo, init?: RequestInit): Promise<Response>;.
Or GlobalFetch could be removed since it's only used as a supertype of Window which already implements WindowOrWorkerGlobalScope anyway.

GlobalFetch has been removed from the spec, so yes, it should be removed.

I'll submit a patch aftec #546 gets merged.

[mhegazy]

#546 will need some legal work too since it adds a new copyright notice, and we need to get MS lawyers to look at it. so it will take some time.

[saschanaz]

GlobalFetch is not there anymore
