Xiang Li c21cd168bb [DirectX backend] avoid generate redundant bitcast in DXILPrepareModule (#65163) ...

When emit NoOp bitcast for GEP Ptr Operand, should use SourceElementType
instead of ResultElementType.

**Behavior Before Change**
Redundant bitcast like 
   ` bitcast ptr addrspace(3) @gs to ptr addrspace(3)`
 will be generated for llvm/test/CodeGen/DirectX/typed_ptr.ll

**Behavior After Change**
  No bitcast will be generated.
