Improvements to unit test behavior.

- Standardize the test timeout implementation using a new TestHandler::SetTestTimeout method and enable timeouts for almost all tests. The test timeout can be disabled globally using a new `--disable-test-timeout` command-line flag.
- Wait for TestHandler object destruction at the end of each test using a new ReleaseAndWaitForDestructor function. This avoids test state leakage and verifies that no object references are leaked.
