[AMD] Update CK for ROCm7

[Paran0idy]

• Remove usage of 'warpSize' variable as it has been deprecated ROCm/composable_kernel#2295
• [BUG] JIT compile fails on ROCm 7.0 (gfx942, PyTorch 2.10.0): constexpr function never produces a constant expression in CK get_warp_size() #1236

Summary by CodeRabbit

• Chores
  • Updated internal dependency reference.

Poem

🐰 A carrot of code, a hop and a bound,
The kernel updated, new wisdom is found,
From version to version, we're hopping along,
Dependencies fresh—our submodules stay strong! 🥕✨

1-1: Verify upstream composable_kernel commit stability and integration testing.

This PR updates the composable_kernel submodule as part of ROCm7 support. Analysis shows that the submodule is automatically initialized during CMake setup but is not explicitly referenced in tilelang's codebase—suggesting it's a transitive dependency (likely via TVM or ROCm SDK runtime).

Since the sandbox environment cannot verify the upstream commit's stability or test runtime compatibility, manual verification is needed to ensure:

1. The new commit (b38bb492a1a55b5abb0c345962143c0f9c482cfb) is stable and properly published in the upstream repository.
2. A full build and test suite pass with the updated submodule to confirm no breaking changes in transitive dependencies.
3. ROCm7 migration is complete and all related CK/ROCm updates are in place.

Recommended manual checks:

• Review the upstream PR: Remove usage of 'warpSize' variable as it has been deprecated ROCm/composable_kernel#2295
• Verify related issue is resolved: [BUG] JIT compile fails on ROCm 7.0 (gfx942, PyTorch 2.10.0): constexpr function never produces a constant expression in CK get_warp_size() #1236
• Run full build and regression tests with the new CK commit to ensure compatibility.
