[mlir][tosa] Make tosa.resize to linalg avoid redundant loads for unit width

When using a tosa resize for ?x1x1x? to ?x1x?x? we should avoid doing a 2D
interpolation as only two unique values are loaded. As the extract operation
performance numerical computation on its values the superfluous extracts may
fail to be coalesced. Instead we only interpolate between the values if there
are multiple values to interpolate between.

For the integer case we also perform scaling by the scaling-factor to apply
the same integer scaling behavior as interpolation.
