COMPMID-3337: Remove write paddings in both axes from CLGEMMMatrixMultiplyReshapedKernel

- Change the interface of STORE_BLOCK_BOUNDARY_AWARE passing the
  conditions on Y and X rather than the X/ coordinates. This allows to
  use the macro with both GEMM reshaped and GEMM reshaped rhs only
- Remove padding from the output tensor of
  CLGEMMMatrixMultiplyReshapedKernel
- Add tests for validating the zero padding requirement
