Sathya Gunasekaran b38bf5b0b1 [api] Change CreationContext to return a MaybeHandle
The current API returns a Handle<NativeContext> which can be
optionally null and all the users of this API never actually
checked for this null value.

Previously, this wasn't a problem as all the possible JSObjects
that were user visible would return a valid NativeContext but now
there are wasm objects that don't have a valid constructor so don't
have a NativeContext.
