Backport of #1112 to 4.0.x.

Summary

Same change as on main: ViewScopeCDIMap.put() returns the previous value instead of the internal ContextualInstanceInfo wrapper.

-return getCreationalContextInstances().put(beanKey, info);
+ContextualInstanceInfo previous = getCreationalContextInstances().put(beanKey, info);
+return previous == null ? null : previous.getContextualInstance();

Evidence

• Before: ViewScopeCDIMapTest.testPutReturnsPreviousValue fails with expected: <first> but was: <...ContextualInstanceInfo@...>
  After: passes; impl 1588 tests, 0 failures, 0 errors (JDK 11, as in the 4.0.x CI)

Merge Danger

Door: two-way

Blast Radius: small

Clean cherry-pick. Only callers using the return value of getViewMap().put(...) with CDI enabled are affected.
