[globals] Remove global shape for Array.from

Type inference currently assumes that a `FunctionSignature`'s effects have no 
false positives. If a `mutate` effect is observed on a read-only place, Forget 
currently assumes this is an user error and 
[throws](https://github.com/facebook/react-forget/blob/207595e04e2be08b8f62bf21dac9d846b9651e43/forget/src/Inference/InferReferenceEffects.ts#L275-L281). 

Array.from is polymorphic -- its effects are dependent on the type of its 
parameters
