opaque_closure: Properly set world for OC from inferred CodeInfo (#49029

)

For OpaqueClosures constructed from inferred code, there is only
one valid age. We were incorrectly setting the primary world age
of the method to `1`, rather than the construction world age of
the opaque closure, causing codegen to fail to emit direct calls
for :invoke'd statements.
