windeployqt: Add output options for simple lists

Some tools, such as MSBuild, can't parse JSON easily. This change adds
a "list" option, which changes the output to list the deployed files, one
per line. The user can view the source, target, or relative target files
by passing -line <source|target|relative> to windeployqt.
