[Inductor] More robust stride and offset extraction from index expressions (#90184)
Currently the stride and offset are determined by substituting 1 and 0 for
different indices, which will fail for any expression that doesn't match the
expected stride calculation. Instead, this uses `sympy.match` and returns `None`
for any variables used in non-standard index calculation, e.g. `torch.roll`
which uses `ModularIndexing`.
