COMPMID-3288: Test improvement for CLGEMMReshapeRHSMatrixKernel (Kernel-level)

Removed configuration tests as they don't add any real value.
Since this is a memory copy kernel, I removed all the large shapes
and created all possible configurations across the 3 data layouts.
From a total of 5957 nightly and 2285 precommit tests now we have
233 in both cases.
