Add "code quality default metric behavior"

[BridgeAR]

Feature request

Description

As a user, I want to change as little as possible so that I have to do less work to achieve my goal.

It is often difficult to understand a map if all three metrics show different things. Mostly people want to change the color and height together and keep the size metric fixed as rloc (with a fallback to loc).

Acceptance criteria

• Add a button (checkbox) that indicates the "program code" default behavior. In case it's set "bind" the height and color metric together and always use the preselected size metric like rloc or loc (done by #1532) for the size metric.

Open questions

• Define where to place the checkbox. Any suggestions are appreciated.
