Fix wamr-ide debugger ignoring launch config (#2155)

The `DebugConfigurationProvider` was overwriting configurations provided
in `launch.json`. In particular, this for example prevented from specifying a
custom port for the debugger.

Example `launch.json`
```
{
    "configurations": [
        {
            "type": "wamr-debug",
            "request": "attach",
            "name": "Attach Debugger",
            "stopOnEntry": true,
            "attachCommands": [
                "process connect -p wasm connect://127.0.0.1:1237"
            ]
        }
    ]
}
```
