Remove special status from "rootValue"

[benjaie]

Description

Prior to this rootValue was required to be a mutable object so we could write to it. We would automatically coerce an undefined rootValue to an object to make this the case. However, this means that any resolver wrappers that people are using source == null on to detect root selection set will fail. So we should remove this to improve compatibility with traditional GraphQL resolvers.

Performance impact

Minimal.

Security impact

None known.

Checklist

Internal refactor.
