[Feat] GraphAr Spark library to support adding new rows/columns

**Is your feature request related to a problem? Please describe.**
In real use cases, the graph data is usually continuously changing, including adding, deleting, and modifying vertices or edges. As part of incremental management functions, we intend to extend the GraphAr Spark tools to support adding new rows/columns conveniently and efficiently.

**Describe the solution you'd like**
Support to add new rows/columns for vertex/edge table and dump the new data by generating new GAR files or appending/rewriting existing GAR files.

**Describe alternatives you've considered**
A clear and concise description of any alternative solutions or features you've considered.

**Additional context**
Add any other context or screenshots about the feature request here.

No files, tests, or entry points are named. Start by locating the GraphAr Spark tools and the vertex/edge table GAR read and write paths. Define the behavior for adding rows and columns, including when to generate, append, or rewrite GAR files, and verify the resulting data for both vertex and edge tables.
