[Fuzzing] Use project reference for PowerRenameLib to fix Debug build link error (#39903)

<!-- Enter a brief description/summary of your PR here. What does it
fix/what does it change/how was it tested (even manually, if necessary)?
-->
## Summary of the Pull Request
This change replaces the manual .lib reference with a proper project
reference to PowerRenameLib in the PowerRename.FuzzingTest project.

Previously, the project used a hardcoded path to link against
PowerRenameLib.lib, which caused build errors in Debug mode when the
.lib file had not yet been generated or the output path was incorrect.
