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}
]
}
}
}
```
