  [mlir][LLVM] Add nsw and nuw flags to trunc (#115509)

This implementation is based on the one already existing for the binary
operations.

If the nuw keyword is present, and any of the truncated bits are
non-zero, the result is a poison value. If the nsw keyword is present,
and any of the truncated bits are not the same as the top bit of the
truncation result, the result is a poison value.
