JH-Leon-KIM-AMD fb3b4011d7 [CK Tile] Grouped conv fwd splitn support (#2776) ...

## What's New
  Add Split-N support for grouped convolution forward to handle tensors >2GB by splitting the batch dimension.

  ## Bug Fix
  Fixed 32-bit integer overflow that caused crashes with 6+ splits:
  - Use `long_index_t` for batch offset calculations
  - Remove redundant GemmM initialization in constructors

  ## How It Works
  - Automatically splits batch dimension when tensor exceeds 2GB
  - Uses grid.z dimension for parallel processing of splits
  - Each split processes a subset of batches independently

  ## Testing
  Verified with tile_example_grouped_conv_fwd:
  - n=3000 (6 splits) ✓
  - n=3500 (7 splits) ✓
  - n=10480 (40 splits) ✓
