Checklist

Please put an x into the boxes that apply. You can also fill these out after creating the PR. If you're not sure, please don't hesitate to ask.

• I have added tests relevant to the introduced functionality, and the unit tests are passing locally
• I have added the test to REGRESSION_TESTS list defined at the top of CMakeLists.txt in tests/CMakeLists.txt, IF the test takes more than 30 seconds to run.
• I have added inline documentation which enables the maintainers with understanding the motivation
• I have removed the stale documentation which is no longer relevant after this pull request
• (If this change is user-facing) I have added release notes which provide the end users with a brief summary of the improvement from this pull request

Pull Request Overview

This PR refactors the grouped convolution code to improve API design by removing the CDElementwise template parameter from GroupedConvTraits and moving it to the kernel arguments level. Additionally, it renames GemmConfig to ConvConfig throughout the codebase for better clarity, and removes unused configuration fields (PermuteA, PermuteB, UseStructuredSparsity, Preshuffle, TiledMMAPermuteN).

• Moved CDElementwise from GroupedConvTraits to GroupedConvFwdKernelArgs template parameters
• Renamed GemmConfig to ConvConfig across all example files
• Removed unused configuration parameters and simplified TileGemmShape and TileGemmUniversalTraits instantiations
