Pull Request Overview
This PR switches the default backend for dygraph-to-static conversion to CINN and adjusts related flags and tests accordingly. Key changes include updating the backend guard and deprecation warnings in the utils and API modules, revising tests to directly assert the new backend behavior, and refactoring code to use the new Backend enum consistently.

| File | Description |
|---|---|
| test/dygraph_to_static/test_jit_backend.py | Added tests to verify CINN and PHI backend behaviors. |
| python/paddle/jit/dy2static/utils.py | Updated backend_guard, introduced infer_use_cinn_backend, and improved flag handling. |
| python/paddle/jit/api.py | Removed deprecated backend check and shifted default backend to CINN. |
| test/deprecated/prim/prim/flags/test_prim_flags_case_deprecated.py | Removed use_cinn parameter from to_static tests in line with backend refactoring. |
| python/paddle/base/core.py | Replaced getenv-based flag retrieval with get_flags for prim control. |
| test/dygraph_to_static/check_approval.py | Updated test approval list to include test_jit_backend.py. |
| python/paddle/jit/dy2static/pir_partial_program.py | Refactored to use the Backend API and updated pass invocation logic. |
| test/dygraph_to_static/test_partial_program_hook.py | Adjusted PirPrimHooker usage to explicitly pass Backend.PHI. |
| python/paddle/jit/dy2static/partial_program.py | Replaced string-based backend checks with Backend's is_cinn() method. |
| test/prim/pir_prim/test_prim_skip_dynamic.py | Switched from os.environ to paddle.set_flags for flag control. |

- [nitpick] Consider rephrasing the deprecation warning for clarity; for example, 'Setting build_strategy.build_cinn_pass is deprecated. Use backend="CINN" to enable CINN instead.' would provide clearer guidance.
warnings.warn("Use `build_strategy.build_cinn_pass = True` to enable CINN is deprecated, please use `backend = 'CINN'` instead.")
python/paddle/jit/dy2static/pir_partial_program.py:1084
- [nitpick] Ensure that the variable naming for the pre-process pass is consistent across the codebase; update any related comments or documentation referencing the old name fused_bn_add_act_pass if necessary.
