No debug on stdout

[zbalkan]

The library UninsallTools should not contain Console.Write* methods as it should be up to the application using the library. Since those are also used for performance metrics and other debug purposes, I used Debug.Write* methods. Also, I allowed null callback just for a really quiet experience.

Thank you for the PR!

• Instead of converting Console calls to Debug calls, I converted them to Trace calls in c962f01, because using Debug would mean these calls would be removed from the release version. I still want them to be written to the application log for debugging purposes.
• I skipped the Made callbacks nullable commit to reduce the amount of changes. Instead, I only cherry-picked the Added quiet and unattended cases in QueryApps commit and edited it use an empty lambda instead of a null in b9a8efc.

I'm closing the PR since it's technically merged, but GitHub didn't pick up on it.
