[FIX][TIRx] Make TilePrimitiveCall serializable

[jinhongyii]

Motivation and context

TilePrimitiveCallNode participates in FFI reflection but did not provide the unsafe-init constructor required to reconstruct an object during deserialization.

Changes

• Add the reflection unsafe-init constructor to TilePrimitiveCallNode.
• Add a pickle round-trip regression that preserves arguments, workspace, config, dispatch, and execution scope.

Testing

• python -m pytest tests/python/tirx/test_op.py
• Changed-files pre-commit checks
