feat(go): add GoVariableContextBuilder and GoFileContextBuilder

- Add GoVariableContextBuilder to handle variable context in Go files.
- Add GoFileContextBuilder to handle file context in Go files.
- Update build.gradle.kts to include Go plugin for Goland.
- Update cc.unitmesh.go.xml to include GoVariableContextBuilder.
- Add plugin.xml for Go plugin.
