Cleanup 'dotnet run file' artifacts

[jjonescz]

• Artifacts of dotnet run file.cs are placed in temp folder on Windows and local app data folder on Linux. The latter seems like our responsibility to clean up periodically. See Use global temp directory for run file outputs #48169 (comment)
• We should also support dotnet clean file.cs.
• Could also support dotnet clean --all-file-based-apps or something like that.
