Support multiple results comparison in benchmark scripts

[Eason0729]

Which issue does this PR close?

Close #13446

Rationale for this change

It would be useful to display the difference among multiple benchmark runs.

See issue.

What changes are included in this PR?

I modify bench.sh and compare.py to accept multiple arguments

Are these changes tested?

Are there any user-facing changes?

No.

[Eason0729]

I spent some time trying to make it(compare.py) more readable, and I ended up with original code.
Let me know if there is a better way to do this.

Anyway, I thinks it ready for review.
