Add custom job scheduling and dependency combiners

- Introduce `CombinedDependenciesJob` for efficient dependency handling and memory management
- Add `ScheduleCustom<T>` for user-defined job execution/free logic
- Refactor `JobInfo` and `JobDataPool<T>` for safer resource management and custom function support
- Improve SPMD extension type constraint formatting
- Update SPMD project content path and increment assembly versions
- Add unit tests for combined dependencies and custom jobs
- Remove `[Timeout]` from tests to prevent spurious failures
- Add TODO for future `WideLane` optimizations
- Replace legacy .sln with .slnx for better solution structure
