  [mlir][Math] Fix IPowIOp folding crash for i1 (#179684)

Fixes #179380: an assertion/crash in math.ipowi constant folding when the result type is i1. 

`IPowIOp::fold` constructed `APInt(width=1, val=1, isSigned=true)`. Signed i1 cannot represent +1 (range [-1, 0]), so APInt asserts (isIntN).

This commit deactivates folding for `i1`.
