f38f9dfb - When tracing SymInts, peephole optimize multiply by one (#85261)

When tracing SymInts, peephole optimize multiply by one (#85261) This shows up a lot in graphs, so it is nice to not bother recording useless info. On pytorch_BERT, this optimization doesn't seem to speed anything up, so it's mostly for cleanliness. Signed-off-by: Edward Z.
