Migrate databricks_catalogs data to Go SDK

[nfx]

This PR also introduces common.WorkspaceData to reduce code boilerplate. The minimal data resource is now to be defined as:

return common.WorkspaceData(func(ctx context.Context, data *struct {
         // now even possible with inline structs!
	Ids []string `json:"ids,omitempty" tf:"computed,slice_set"`
}, w *databricks.WorkspaceClient) error {
	catalogs, err := w.Catalogs.ListAll(ctx)
	if err != nil {
		return err
	}
	for _, v := range catalogs {
		data.Ids = append(data.Ids, v.Name)
	}
	return nil
})
