tool-cache: make extract functions quiet by default and more verbose if core.isDebug is set (#206)

* tool-cache: make unzip and 7z extract quiet by default

This avoids spamming the log when unzipping large archives.

* tool-cache: make tar, unzip and 7z verbose when `core.isDebug`

Make the extract function print the list of extracted file if
the action is run in debug mode.
