Tibor Vass 4f76283213 builder: use buildkit's GC for build cache

This allows users to configure the buildkit GC.

The following enables the default GC:
```
{
  "builder": {
    "gc": {
      "enabled": true
    }
  }
}
```

The default GC policy has a simple config:
```
{
  "builder": {
    "gc": {
      "enabled": true,
      "defaultKeepStorage": "30GB"
    }
  }
}
```

A custom GC policy can be used instead by specifying a list of cache prune rules:
```
{
  "builder": {
    "gc": {
      "enabled": true,
      "policy": [
        {"keepStorage": "512MB", "filter": ["unused-for=1400h"]]},
        {"keepStorage": "30GB", "all": true}
      ]
    }
  }
}
```
