[CK] Fix aiter tests in CI (#5011)

## Motivation

Updates the CK/AITER CI Docker build to source Composable Kernel either
from `ROCm/rocm-libraries` (via sparse-checkout) or directly from
`ROCm/composable_kernel`, aiming to make aiter tests reliable in CI.

**Changes:**
- Added a build arg to toggle fetching CK from `ROCm/rocm-libraries`
(enabled by default).
- Implemented sparse-checkout + local re-init/commit flow to materialize
CK into a local `ck/` directory.
- Updated aiter’s CK vendoring step to clone from the locally prepared
`ck/` directory.
