repmat accepting Int only

Could the signature be relaxed to accept generic Integers? (I guess yes :)

near-duplicate of #17372

near-duplicate of #17372

In that case the signature of reshape was tightened to avoid some weird consequences (obtaining ReshapedArray instead of Array). I guess that it is safe to relax repmat instead, right?

Any reason this was reopened? Fixed by #20113
