Would you mind to align the patch with functions_select_1d.hpp? Looks like it could be done by applying the comments from #875. I might easily miss something.

@v-klochkov Would you mind to review this PR?

Looks good to me.

Can you please add one more separate test that would check zero and/or negative 'offset' and 'stride' cases?

@v-klochkov Stride should be equal or greater than zero

include\sycl/ext/intel/esimd/detail/region.hpp:41:3: error: static_assert failed due to requirement 'Size_x > 0 && Stride_x >= 0' "illegal region in x-dimension"
  static_assert(Size_x > 0 && Stride_x >= 0, "illegal region in x-dimension");
  ^             ~~~~~~~~~~~~~~~~~~~~~~~~~~~

In case Offset is negative behavior is not clear (additional discussion is required) and I suggest to update coverage for simd 2d select in separate PR.
@v-klochkov what do you think about this?

One more point. Is it OK to have separate PR for this test? We would have tests from this PR in CI with no delay.
