Dolphin settings re-layout (small scope)
Motivation: After a user asked a question in the general KDE chat, where they wouldn't find the setting to make folder size use the content sizes, I started looking for it, and was kind of surprised that it belongs to the Details View. Trying to find a better place for it, I stumbled upon the different settings pages and came out with this proposal.
Note that the scope is small, and it simply tries to move some settings around and re-group them a more (IMHO) logical place to improve the situation in a manageable short-term. Larger scoped refactors can take longer time to agree on and have a higher risk of bike-shedding
I also kind of recall there has been some (recent?) proposal on this same topic. Sorry if this stepping into some work-on-progress. I couldn't quickly find a reference to that work.
