[clang] [Modules] Enable MS Windows test for implicit-module-no-timestamp.cpp (PR #91738)

[Ivan Murashko via cfe-commits]

https://github.com/ivanmurashko created https://github.com/llvm/llvm-project/pull/91738

There is a followup commit for #90319. The windows test was disabled at that commit but it should pass on MS Windows and it would be good to have it enabled.
