qmlformat: Distinguish between options that control I/O vs. options that control a QML document's format

qmlformat supports 2 broad categories of options:

A) Options that control how qmlformat reads inputs and writes outputs (examples: --files, --verbose, --help)
B) Options that control how qmlformat lays out the contents of a QML document (examples: --tabs, --indent-width, --normalize)

The .qmlformat.ini file is only concerned with Category B options.

It would be helpful to split qmlformat --help as well as https://doc.qt.io/qt-6/qtqml-tooling-qmlformat.html#options into the 2 sub-categories.

(Background context: We received a request to add the equivalent of qmlformat --inplace into .qmlformat.ini. Categorizing the options would help to clarify why this request doesn't make sense)
