Cecil represents modreq/modopt in signatures as part of the TypeReference (using subclasses RequiredModifierType/OptionalModifierType). We need to unwrap these to get the correct behavior in IsNamedType.
This fixes the
IsTypeInterestingForDataflowcheck for modreq/modopt types (Type modreq(IsVolatile)should be considered interesting for dataflow, andType[] modreq(IsVolatile)should not). Includes a similar fix for function pointers.Discovered while adding trim annotations in #108464.
