Display Controls size when determined by Container

[markdibarry]

Describe the project you are working on

A 2D game with menus

Describe the problem or limitation you are having in your project

When a Control's size is determined by its Container, the editor now hides the size because it shouldn't be editable. However, oftentimes it's necessary to know what the size is, and now the only way to determine it is via running the game and debugging (which can crash the program in C#) or printing to the console (tedious).

Describe the feature / enhancement and how it helps to overcome the problem or limitation

The size for Controls that are inside Containers should be exposed as an un-editable field.

Describe how your proposal will work, with code, pseudo-code, mock-ups, and/or diagrams

Same as it is in 3.x, but not editable.

If this enhancement will not be used often, can it be worked around with a few lines of script?

Yes, but it's tedious or crash-y for how often it's needed.

Is there a reason why this should be core and not an add-on in the asset library?

This is a modification to a core feature.

I am for making it optional, and maybe hidden by default, but also allow to see controls position, and maybe even rotation - for example for those who animates buttons inside containers
