feat(composablekernel): [CK][CK_TILE] Add batched contraction
 multiple ABD (#6339)

## Motivation

This PR brings multi-ABD contraction support to CK-Tile, unifying
multi-tensor fusion from UniversalGemmKernel / GemmKernelMultiABD with
multi-dimensional tensor contraction from BatchedContractionKernel.

ISSUE ID : AICK-228

## Technical Details

Added the following:
- batched contraction multiple ABD op added to ck_tile
- ckTileEngine support
- unit-tests
- example

## Test Plan

Build test_ck_tile_contraction_multi_abd_cshuffle and
test_ck_tile_contraction_multi_abd_default2d inside the ROCm Docker
container.
Run GTest suites which verify GPU kernel output against CPU reference
within computed relative/absolute tolerance thresholds.

## Test Result

Both test targets compile cleanly with no warnings/errors on gfx942.
All test cases pass GPU-vs-CPU verification.
