Add fusion rules for the zipWith functions in base (#15263)
This patch will allow `zip3` and `zipWith3` in `GHC.List` as well
as `zipWith4`, `zipWith5`, `zipWith6` and `zipWith7` in `Data.OldList` to fuse.
These rules are kept in a similar style as the rules for `zip` and `zipWith`.
Added a corresponding test case.
Test Plan: validate
