Pull Request Overview
This PR enhances the reliability of tests that check for weak reference collection by replacing direct GC calls with retry-enabled helpers.
- Replaces
await Task.Yield(); GC.Collect(); GC.WaitForPendingFinalizers();withawait TestHelpers.Collect()in most tests. - Introduces
TestHelpers.WaitForCollect()to await object collection and uses it in assertions. - Updates
TestHelpers.Collect()to perform multiple forced collections and adjusts test code to use non-genericWeakReference.

Description of Change
While working on #29837 a number of the tests related to checking for weak references were failing intermittently. This PR adds retries to all tests related to checking for weak references to ensure that the tests are more reliable. With these changes I wasn't able to get it to fail locally.
