Add an editor setting to adjust the size of 2D manipulation gizmos

[ModuleCode]

Describe the project you are working on

Demo2D

Describe the problem or limitation you are having in your project

2D mobile Tools and ScaleTools have a very short grasp area, I think there should be an editor Settings option to let users set the length of ScaleTools and move tools

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

Adds the tool's length option to the editor Settings

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

This is just my idea (put this option in 2D), the actual situation can be discussed and decided

Before

After

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

no

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

yes

[ModuleCode]

The zoom tool is also small, and this should be added to the Settings too

I'd call it Gizmo Scale or similar, as "length" doesn't make sense for all the gizmos, and is more direct

[Calinou]

I'd check first to make sure whether the 2D gizmos are scaled according to the editor scale (screenshots in OP use editor scale above 100%). If they aren't, that's a bug.

[KoBeWi]

There is already interface/touchscreen/scale_gizmo_handles, which affects at least some of the gizmos.

[ModuleCode]

emmm It just modifies the size of the selection pattern,

[ModuleCode]

The Gizmo Scale is still small

[AThousandShips]

From a glance at the code EDSCALE is used, unsure if it is used ccorrectly though

Also increase the size/width or edit lines in UI , Collision, and etc. it's very small
