Thank you @vlad-perevezentsev for implementing the significant performance improvement. No more comments from me.

This PR suggests updating `dpnp.isclose()` function adding a scalar-specific SYCL kernels for both contiguous and stride cases to improve performance when `rtol` and `atol` are scalars. Also extends and updates tests for `dpnp.isclose()` The new kernel **improves performance** by **up to 10x** compared to the previous implementation when `rtol` and `atol` are scalars (tested on PVC). c9b9f70
