Remove CoordX and CoordY arguments of OpCooperativeMatrixPrefetchINTEL

According to a new specification, CoordX and CoordY parameters are not needed for prefetch in CooperativeMatrixPrefetchINTEL(), only offset pointer is enough. This PR is to fix support for joint_matrix_prefetch in SPIRV according to the new specification.
