[CK] contraction: extend GetTypeString() to include layout-differentiating params (#6022)

## Motivation

Consumers that identify kernels by their `GetTypeString()` (such as
hipTensor's actor-critic kernel selection, which hashes the string into
a
stable cross-platform UID) were silently dropping one of two colliding
variants during registry insertion.

`GetTypeString()` in `DeviceContractionMultipleD_Xdl_CShuffle`
previously
printed 13 template parameters, omitting
`ABlockTransferSrcScalarPerVector`,
`BBlockTransferSrcScalarPerVector`, `ABlockLdsExtraM`, and
`BBlockLdsExtraN`.

These four parameters determine the block-transfer access width and LDS
padding strategy, and are precisely what differentiates the `kk`, `kn`,
`mk`, and `mn` layout variants from one another when all other geometry
parameters are equal. Two instantiations with identical 13-parameter
strings
are distinct C++ types that accept different stride layouts and reject
each
other's arguments via `IsSupportedArgument`.

This patch extends the output to 17 parameters so that every distinct
template instantiation of this class produces a unique
`GetTypeString()`.

## Technical Details


`include/ck/tensor_operation/gpu/device/impl/device_contraction_multiple_d_xdl_cshuffle.hpp`:
- extend `GetTypeString()` from 13 to 17 parameters including
`ABlockTransferSrcScalarPerVector`,
`BBlockTransferSrcScalarPerVector`, `ABlockLdsExtraM`, and
`BBlockLdsExtraN`.
    
## Test Plan

Build CK and hipTensor with these changes, and verify hipTensor can
differentiate and select the
correct kernels with layout variations.

## Test Result

CK is building correctly and hipTensor is selecting the kernels
correctly.
