fold: Remove (rrotate (rrotate A CST) CST) folding [PR117492]

This removes an (broken) simplification from fold which is already handled in match.
The reason why it was broken is because of the use of wi::to_wide on the RHS of the
rotate which could be 2 different types even though the LHS was the same type.
Since it is already handled in match (by the patterns for
`Turn (a OP c1) OP c2 into a OP (c1+c2).`). It can be removed without losing any optimizations.

Bootstrapped and tested on x86_64-linux-gnu.
