Print more diagnostic information

I see this today:

ms-dotnettools.csharp tried to install .NET 9.0.2~arm64 but that install had already been requested. No downloads or changes were made.
ms-dotnettools.csharp requested to download the .NET Runtime.
Downloading .NET version(s) 9.0.2~arm64 ............ Done!
.NET 9.0.2~arm64 executable path: c:\Users\rlander\AppData\Roaming\Code - Insiders\User\globalStorage\ms-dotnettools.vscode-dotnet-runtime\.dotnet\9.0.2~arm64\dotnet.exe

Please consider:

• Report all files downloaded (including JSON and scripts)
• Report times for each
• Report total download time

This information would make it much easier to share bad download time diagnostics with us. We could even include an email address and/or issue for them to report long download times.

This would also be more informative for us as the team building this experience. It's often easy for us to ignore problems that are not "in our face".

That's a good idea. We may need to do this in tandem with adding a less verbose mode because users have already pointed out that these messages frustrate them and they want to turn them off.

Yup. That sounds smart. I also often don't want the noise I see from the extensions. I appreciate it being there when needed but hidden from direct view.

Please include info about files skipped due to TTL or similar.
