<pre>
    The `uadd_with_overflow` intrinsic should be made scalarizable.

The primary use-case that spawned this issue is to be able to have its vector form be scalarized so that it can be lowered to several `UAddc` DXIL ops which perform the same function on scalars.

Some issues/PRs that benefit from this change:
- #99205 
- #125319
