issue: #42523
Resolve deadlock issue in GroupedAllocator where resource release
notifications fail to propagate across hierarchy levels, causing child
allocators to wait indefinitely.
Changes include:
- Add recursive notify() method to GroupedAllocator
- Ensure all child allocators receive resource release notifications
- Fix TOCTOU race condition in hierarchical resource management
This resolves the intermittent test timeout in TestGroupedAllocator test
that exhibited deadlock due to missed condition notifications.
