[TLE] Feature/extrac tile strides new

[lzllx123]

Summary:

1. [TLE]Add optional strides parameter to tle.extract_tile and tle.insert_tile, enabling strided tile extraction/insertion.
2. Adapted for NVIDIA and GCU backends.

API Changes:

1. Python: extract_tile(x, index, tile_shape, strides=None) / insert_tile(x, tile, index, strides=None)
2. MLIR: Tle_ExtractTileOp and Tle_InsertTileOp added OptionalAttr:$strides
3. Backward compatible: defaults to tile_shape when omitted

Performance:

New tutorials optimized with tle.extract_tile / tle.insert_tile:

1. 05-glu.py (GLU)
2. 06-2D_Depthwise_Conv.py (2D Depthwise Conv)
3. 07-causal-conv1d.py (Causal Conv1D)
4. 08-rope.py (RoPE)

CI:

Added lightweight correctness tests for tutorials 05-08 in hopper-build-and-test.yml.

Requesting changes before merge:

1. Please replace the Chinese comments with English. I found Chinese comments in:

   • python/triton/experimental/tle/language/gpu/semantic.py:118
   • python/test/tle/unit/test_insert_tile_static_index.py:93
   • third_party/tle/dialect/lib/Transforms/ExtractTileToLLVM.cpp:40

   Comments in source and tests should be readable by all maintainers.

2. Please expand the PR summary. The current summary only states that strides was added to tle.extract_tile and tle.insert_tile. It should explicitly document the changed APIs, including the Python API surface and any corresponding TLE/MLIR op attribute changes. It should also state which operators show performance improvement and include the measured before/after numbers or speedups, for example GLU, 2D Depthwise Conv, Causal Conv1D, and RoPE if those new tutorials are the performance evidence.

3. Please add the newly introduced tutorials to CI. This PR adds:

   • python/tutorials/tle/05-glu.py
   • python/tutorials/tle/06-2D_Depthwise_Conv.py
   • python/tutorials/tle/07-causal-conv1d.py
   • python/tutorials/tle/08-rope.py

   However, the Hopper TLE tutorial workflow still only runs the existing tutorials through 04-cluster-gemm.py plus the DeepSeek examples (.github/workflows/hopper-build-and-test.yml:122 and .github/workflows/hopper-build-and-test.yml:180). Please add lightweight correctness invocations for the new tutorials, such as the existing --only_unit_test paths for 05/06 and non-benchmark correctness runs for 07/08, or add equivalent CI test targets so these examples do not land untested.

@sunnycase
All three requested items have been fully resolved:

1. All Chinese comments in the three listed source and test files are replaced with standard English.
2. The PR description has been expanded completely, including full documentation of modified Python APIs, corresponding TLE/MLIR op attribute adjustments, and complete measured speedup benchmark data for GLU, 2D Depthwise Conv, Causal Conv1D and RoPE.
3. Added lightweight correctness test targets for the four new tutorial files in the Hopper CI workflow, following the existing --only_unit_test pattern, to ensure all new tutorials will be validated during CI runs.
