This PR enhances the symbolic expression upper bound estimation in static memory planning. Prior to this PR, we are not able to estimate the upper bound of `a * b` when `a` has an upper bound while `b` does not. This PR enhances the estimation with arith::IntSet. We introduce another TIR attribute `tir_non_negative_var` to indicate the non-negative TIR variables for memory planning use. A new unit test is introduced for this enhancement.
