[CK_TILE] Changed cshuffle LDS descriptor to naive layout (#5729)

## Motivation
This PR changes gemm/convolution cshuffle layout into plain one. to
improve cshuffle operation performance.

## Technical Details
The purpose is that before this change the cshuffle layout was having
some descriptor transformations that were probably aimed at reducing LDS
bank conflicts, but the transformations itself were terribly slow, which
negatively impacted the performance.

## Test Plan
There is no need for additional tests, since current tests cover this
functionality.
