COMPMID-3323: Add cl_image support for GEMMReshapedOnlyRHS T

- Added support for cl_image in CLGEMMMatrixMultiplyReshapedInlyRHSKernel (both NT and T kernels)
- Extended the tests for the validating rhs_info.export_to_cl_image = true
- Updated doxygen documentation in CLGEMMMatrixMultiplyReshapedOnlyRHSKernel.h
