OperatorEntry: Avoid unnecessarily templated code (#67986)
Summary:
`assertSignatureIsCorrect` is instantiated at minimum once per unique operator signature yet its core logic is independent of the type. So, it makes sense to have a light-weight template that does nothing but call into the non-templated function with the correct `CppSignature` object.
