* feat(arg_binder): enhance shape variable handling and assertions

- Implemented special handling for comparing if_then_else expressions to simplify conditions involving NULL checks.
- Added methods to set shared shape variables and finalize deferred bindings, generating cascading if_then_else expressions and runtime assertions for non-NULL buffers.
- Updated the binding logic to defer shape variable bindings for shared variables, ensuring proper handling across multiple nullable buffers.

* refactor(arg_binder): clean up shape variable handling and remove unused code

- Removed deprecated methods for setting shared shape variables and finalizing deferred bindings, streamlining the argument binding process.
- Simplified the logic for handling shape values in the `BindDLTensor` function, ensuring immediate binding for normal shape variables.
- Enhanced clarity by eliminating unnecessary comments and code related to cascading if_then_else expressions for shared variables.

* refactor(arg_binder): enhance DLTensor binding with improved shape handling

- Replaced the single `BindDLTensor` method with `BindDLTensors` to support multiple buffers, improving flexibility in handling DLTensor bindings.
- Introduced a two-pass approach for shape variable handling, allowing for better management of symbolic dimensions and null checks.
- Updated the logic to assert non-null conditions at runtime and utilize cascaded if_then_else expressions for shape retrieval, enhancing robustness.
- Removed deprecated code and streamlined the binding process for clarity and maintainability.

* fix(test_nullable_buffer_params): improve formatting and consistency in test output

- Updated string formatting for better readability in the `test_nullable_shared_shape` function.
- Ensured consistent use of double quotes for string literals.
- Added a missing newline at the end of the file for proper formatting.

* refactor(arg_binder): simplify allocation size calculation in BindDLTensors

- Streamlined the calculation of allocation size by replacing a lambda function with a direct loop, enhancing readability and maintainability.
- Improved clarity in the null check message for data pointers, ensuring better understanding of the binding process.

* Remove debug prints from phase.py

Removed debug print statements after MakePackedAPI transformation.
