[super] Optimize super property access in JSNativeContextSpecialization
This is the second reland of
https://chromium-review.googlesource.com/c/v8/v8/+/2487122 , this time
without RuntimeCallStats in the tests.
Generalize the existing property lookup machinery
(JSNCS::ReduceNamedAccess) to handle the case where the
lookup_start_object and the receiver are different objects.
