Subject: [PATCH 23/30] qml tool: Use QCommandLineParser::process() rather than
 parse()

This handles the --version, --help and --help-all options.
Apparently there's no other way to handle --help-all, because
addHelpOption() adds two options but only returns one of them.
Amends bb6602bca2b20d98f24320b10c7a039e605c9a05

Fixes: QTBUG-100678
Pick-to: 6.2 6.5 5.15
Change-Id: Iddd1ba2dae975d7256935d8d357e2f3ac6c013d6
