We also need a test for the case when arrays have different allocation queues.

q0 = dpctl.SyclQueue()
x0 = dpt.arange(5, sycl_queue=q0)
q1 = dpctl.SyclQueue()
x1 = dpt.arange(3, sycl_queue=q1)
mgr = dpt.meshgrid((x0,x1))

Is this expected to work with resulting arrays keeping the same allocation queues as inputs for "xy" and appropriate permutation for "ij"? Or should this raise?

Added test to check for this case.
