  [mlir][arith] Reject signful integer element types in `arith.constant` (#204937)

Update arith.constant verification to reject integer constants with
signed and unsigned element types including shaped constants like
tensors and vectors, as the arith dialect does not support
signed/unsigned types.

This incidentally address cases where further lowering would crash (e.g.
SPIR-V constant lowering used IntegerAttr::getInt() on an unsigned
integer attribute from tensor<2xui8>)

Fixes #204911
