PR #<!-- -->205586 refactored existing tests and created a new test `clang-tools-extra/test/clang-doc/html/long-name.cpp` which when run on Windows generates a file that exceeds the maximum path length, leading to the directory not being able to be easily deleted. From my bot:
```

When looking into this, I noticed that there was a practically identical test checked in as `clang-tools-extra/test/clang-doc/json/long-name.cpp` that was marked as `UNSUPPORTED: system-windows`, so this change extends that to this similar test as well.

This should fix build bots being unable to successfully clean the build directory between runs. See https://lab.llvm.org/buildbot/#/builders/46/builds/37142 for an example of a build where the deletion of the build directory failed. The previous run was where the change was first run on the bot and would have introduced the problematic files.
