Improve/Impl (graph) property based vectorization

Currently, our current vectorized logic is as follows:
1. text vector (raw)
2. graph vector
- vid(vertexID) based vector
- property based vector
```mermaid
graph TD
A["Text (raw)"] --> B("Text Vector - chunk");
A --> C("Graph - Vertices/Edges extract from Text");
C --> D("Graph Vector");
D --> E("VID based Vector - Relatively complete");
D --> F("Property based Vector - Primitive, needs improvement");

%% Style to highlight the primitive part
classDef primitive fill:#f9f,stroke:#333,stroke-width:2px;
class F primitive;
```

The vectorization of `vid` is relatively complete, but the vectorization based on **vertex/edge** property is still relatively **primitive** and needs to be improved in its implementation and application(Could search in the code for details)
