Support More Cases in NoOpElimination (#13460)
Current NoOpElimination can support only Add node. This PR adds support
for: x-0, x*1, 1*x and x/1 besides x+0 and 0+x.
With this PR, all Div(x,1) and their gradients (also Div(x,1)) in
Huggingface's diffusers model can be removed, which takes ~1% of compute
time in total previously.
