Fix DLPack С-contiguous stride reconstruction

[vlad-perevezentsev]

Previously C-contiguous arrays with ndim > 0 were exported with NULL strides while F-contiguous strides were computed explicitly.
In #2193 NULL strides are no longer allowed due to DLPack v 1.2 and missing strides started to be
computed using only F-order logic so C-contiguous arrays were exported with incorrect strides

import dpctl.tensor as dpt

a = dpt.asarray([[1,2,3],[4,5,6]])
a.strides
# (3, 1)
b = dpt.from_dlpack(a)
b.strides
# (1, 2)

This PR adds stride computation for C-contiguous layouts and resolves #2213
