Improve settings UI

[mathrick]

Hi, this PR improves the settings dialogue UI, making it significantly more compact, and IMHO, also easier to understand and nicer to look at.

Before:

After:

The changes are split into three commits

1. Remove the value sets of settings from the user-facing help strings. Fixes GD-539: Settings UI help strings should not include internal data #539
2. Improve the wording of the help strings themselves (more detailed description in the commit message). Fixes GD-540: Improve user-facing help strings in settings UI #540
3. Improved sizing logic for the grid views displaying the settings, meaning less space is wasted, and huge amounts of unused space don't make the scrollbars huge unnecessarily. Not every tab in the dialogue is currently able to fit in without scrolling on my laptop, but some of them are, and it's generally much nicer. Fixes GD-541: Settings dialogue reserves way more horizontal space than it needs, leading to huge scrollbars #541

I did not make any changes to the settings themselves, everything is as it was before and split across tabs in the same way. I did a full test suite run locally, and everything works aside from the C# tests, which I did not run, as I'm not using Godot Mono.

Hello, thank you for your contribution to this project.

Please be so kind and create another refactoring ticket detailing what you want to achieve and link it to the PR.
It should point out existing problems and possible solutions.
It would be good to have a before/after screenshot in the PR, which can then also be used later for the release notes.
I'll take a look at your changes later today.

I have checked the changes and looks good.
A have only find minor things, please check my comments.

In addition, the actual dialog size can be shrinking because the properties are now more compact and well sized.
I tried with using reset_size() after component creation but without success, maybe you can fix this too.

Great Job, Thanks

I made the refactoring tickets, I'll take some screenshots and attach them later today.

Yeah, I ran into that too :(. It seems that no matter what I do, the actual dialogue size won't budge. I don't really understand the way Godot windows work, so I had little luck getting it to do what I want. I tried changing the size in the saved scene, but that value is apparently just completely ignored. The thing that displays on my screen has a completely different shape than what is shown in the 2D editor preview.
