Construct a (sub)graph with serialized files (`.gsf`, graph serialized format/file)

As titled, this is a successor task of #1587 optimized for this scenario:
- a large graph `g1`, serialized to files, each file with one label, e.g., v1.gsfv, v2.gsfv, v3....., e1.gsfe, e2.gsfe....
- `g1` surely can rebuild from serialized files, when issue-1587 is done.
- now we may want to build a `g2`, with subset of vertex/edge labels of `g1`, says, v1.gsfv, v2.gsfv, e2.gsfe...
- an optional approach: build a new graph schema, load data from .gsf files.
