Improve mysql installation

* Instead of deleting the files from a previous installation, which will
  not actually release any disk space but just make the qcow2 file
  larger, let's just rename the directory the old files are in.
  That is a significantly faster operation.
* When extracting the zip archive, only extract what we need for Qt:
  Libraries, binaries and headers. We can skip the installation of
  several thousand documentation files for example, which takes a long
  time.
* Instead of downloading the zip archive via PowerShell's
  Invoke-WebRequest we can get the data much faster using CopyItem off
  the CIFS share. As a bonus this is also more robust against download
  failures.
