std-widgets: added LayoutSettings global

Fixes #6698

Thanks, I think it make sense to expose the layout margin and padding through a global.

I don't think the text-cursor-width make sense to be exposed though. This is also not related to layout.

As for the name LayoutSettings, this means it is specific to layout, but could it be used for other settings in the future?
Also are these really "Settings"? Settings implies that you can change them. Maybe they are StyleParameters or StyleProperties?

@ogoffart the text-cursor-width is removed now.

For the name I'm open for an alternative. LayoutSettings is just a suggestion from my side. I would like to make the name more layout specific. Because we will have also something for the font settings.

Suggestion

// Brushes
global Palette { ... }

// Font settings e.g. TextStyles.header.font-size, TextStyles.header.font-weight
global TextStyles { ... }

global LayoutParameters { ... }

What you you think?
