Forms are not using wide mode

[rinigus]

In Kirigami, preferences in wide mode are wider than the allocated page. Same goes for routing options and such

typo in commit description - partially fixed by disabling wide mode in a7f6e6e

[rinigus]

In wide mode, Kirigami form layout tends to overcommit the width of the form. My usage and Kirigami assumptions don't match somewhere, have to find a balance. Have to make simple example and ask for feedback.

Examples:

I can't figure out how to make FormLayout to display label: text with the text filling as much width as possible. looks like Layout.fillWidth is ignored.

In addition, buddyFor is broken. Try to move https://github.com/KDE/kirigami-gallery/blob/master/src/data/contents/ui/gallery/FormLayoutGallery.qml#L97 somewhere and it will be ignored.

Seems like buddyFor is resolved.

Now need to get resolution for https://bugs.kde.org/show_bug.cgi?id=435066
