  [mlir][llvm] Support nusw and nuw in GEP (#137272)

nusw and nuw were introduced in getelementptr, this patch plumbs them in
MLIR.

Since inbounds implies nusw, this patch also adds an inboundsFlag to
represent the concept of raw inbounds with no nusw implication, and have
the inbounds literal captured as the combination of inboundsFlag and
nusw.

Fixes: iree#20482
