fix(expect-utils): handle cross-realm constructors in toStrictEqual

[JamieMagee]

Summary

structuredClone runs in the outer Node.js realm, so its return values have different constructor references than objects created inside Jest's VM context. This made toStrictEqual fail with "serializes to the same string" for every built-in type (plain objects, Maps, Sets, Dates, RegExps).

When constructors don't match by identity, we now check if both are native built-ins with the same name. User-defined classes still require identity equality.

Changed typeEquality and iterableEquality in expect-utils/src/utils.ts.

Fixes #14011

Test plan

10 unit tests added using vm.createContext() to create cross-realm objects. Covers all affected built-in types, plus a negative case for user-defined classes with the same name.
