[Refactor] Phaseout PassConfig `kDisableDynamicTailSplit` and... 

[Refactor] Phaseout PassConfig `kDisableDynamicTailSplit` and `kDynamicAlignment` as they are legacy (#1486)

* [Cleanup] Remove dynamic shape example and related tests

* Deleted the dynamic shape example script `example_dynamic.py` and its corresponding test file `test_example_dynamic.py` to streamline the codebase.
* Removed unused dynamic tail split and dynamic alignment configurations from `builtin.h` and `pass_config.py`.
* Cleaned up the dynamic shape testing files to eliminate redundancy and improve maintainability.

* build fix
