Db v4 move graph folder

[arienandalibi]

What changes were proposed in this pull request?

Move graph_folder.rs constants (directory and file names regarding exported graphs) out of the raphtory crate and into raphtory-api.

Why are the changes needed?

Following previous changes, we needed access to GRAPH_META_PATH in pometry-storage, where we can't import from raphtory.

Does this PR introduce any user-facing change? If yes is this documented?

No
