Have a way to set the launch target in function of the chosen build target

In other words, if I build my app, than I wanna launch my app. If I build my tests, than I wanna launch my tests.
I would propose something like :

"makefile.buildConfigurations": [
        {
            "name": "default",
            "defaultLaunchConfiguration": "nameOfMyAppLaunchConfiguration",
        },
        {
            "name": "test",
            "defaultLaunchConfiguration": "nameOfMyTestLaunchConfiguration",
        }
    ]

OR

"makefile.buildConfigurations": [
        {
            "name": "default",
            "defaultLaunchTarget": "nameOfMyAppLaunchTarget",
        },
        {
            "name": "test",
            "defaultLaunchTarget": "nameOfMyTestLaunchTarget",
        }
    ]

When we change the build target, the launch target gets updated to the specified value. The launch target is not updated when no value is specified.

Start by tracing how build configurations and launch targets are represented and updated in the extension. Compare the two proposed settings approaches and check any existing configuration or launch-target tests and documentation. Done means changing a build target updates its configured launch target, while configurations without a value leave the launch target unchanged.
