  [DirectX] Support ConstExpr GEPs (#150082)

- Fixes #150050
- Address the issue of many nested geps
- Check for ConstantExpr GEP if we see it check if it needs a global
replacement with a new type. Create the new constExpr Gep and set the
pointer operand to it. Finally cleanup and remove the old nested geps.
