exp: Update --rev to support append action.

Closes #9390

[sroy3]

Would it be possible to specify the number of commits for each rev also?

Do you mean separately? You can specify --num but the same value will be applied to all the passed rev

Yes, separately (ex.: only 1 for a branch and 5 for the other one)

That would require additional work both on the CLI level and the internal API level

BTW @sroy3 , it would require you to build a more convoluted set of args, but with this P.R. you could achieve that behavior using git suffixes, like:

$ dvc exp show \
--rev main --rev main~1 \
--rev other-branch --rev other-branch~1 --rev other-branch~2 ...

It's not doing quite the same thing. It's showing the nth previous commit instead of show n previous commits. I'm sorry, I didn't understand it right the first time. You're right, it works well and would be enough.
