1a8c6130 - [mlir][arith] Align shift Ops with LLVM instructions on allowed shift amounts (#82133)

[mlir][arith] Align shift Ops with LLVM instructions on allowed shift amounts (#82133) This patch aligns the shift Ops in `arith` with respective LLVM instructions. Specifically, shifting by an amount equal to the bitwidth of the operand is now defined to return poison.
