Fixes #2561
Add an experimental e-graph equality saturation framework for the KQIR
optimizer to generate better query plans.
* **New Pass Implementation**
- Add `EGraphEqualitySaturation` class in
`src/search/passes/egraph_equality_saturation.h` and
`src/search/passes/egraph_equality_saturation.cc`.
- Implement the `Transform` method to perform equality saturation on the
e-graph.
* **Integration with Existing Code**
- Update `src/search/ir_pass.h` to include the new pass.
- Update `src/search/passes/manager.h` to include the new pass in the
optimization sequence.
* **Testing**
- Add unit tests for the `EGraphEqualitySaturation` pass in
`tests/cppunit/egraph_equality_saturation_test.cc`.
- Test various scenarios to ensure the correctness of the equality
saturation framework.
