Tianqi Chen 1bb5cf6102 [REFACTOR][IR] Unify StructInfo and Type (#19853)
## Summary

- unify Relax's former StructInfo surface into the Type vocabulary and
Expr.ty storage path
- remove leftover DependentTypeNode and legacy OpNode::op_type storage
- keep base Type nullable while concrete Relax/DTensor type refs are
non-nullable
- clean stale StructInfo/TensorStructInfo/sinfo vocabulary in
Python/docs and distributed-op macros
- address Gemini follow-ups for parser annotations, BlockBuilder
docstring, and Adreno TensorType cast audit
