* [Dev][Bugfix] Add RMS Normalization Kernels and Fix Reduce Bug

- Implement two RMS normalization implementations in TileLang:
  * `rms_norm_splitk`: Split-K reduction approach for large matrices
  * `rms_norm`: Full reduction kernel with simplified implementation
- Add reference implementation using PyTorch for validation
- Include performance benchmarking for both kernel variants
- Demonstrate flexible block size and matrix size configurations

* [Examples] Simplify RMS Normalization Kernel Compilation

- Remove commented-out code for split-K RMS normalization
- Simplify kernel compilation by removing explicit TMA lowering configuration
- Update copyright header to Tile-AI Corporation
- Streamline main script for RMS normalization example
