Resolve Type-Based Overload Issue in Compute Functionality

### Issue Description:
In the current state of the [GraphoscopeRestructure branch](https://github.com/fslaborg/Graphoscope/tree/GraphoscopeRestructure), the compute functions for directed and undirected FContextMaps are facing a challenge where they cannot share the same name. Consequently, they have been temporarily separated into compute and computeUndirected. This distinction was introduced as a workaround until a more sustainable solution can be implemented.
