toolchain.prf: Use vswhere to obtain VS installation path

Beginning with Visual Studio 2017, vswhere should be used to discover
Visual Studio installations. Installations of 2019 and up are not even
registered inside the registry anymore, so vswhere is the only way to
obtain information about these.
