This change is the first in a series to add support for git's commit-graph. This should speed up commit graph traversals by avoiding object parsing and allowing some operations to terminate earlier. Part of: libgit2#5757
This change introduces `git_commit_graph_entry_find()` and `git_commit_graph_entry_parent()`. These two functions allow a much faster lookup of commits by ID, since the ODB does not need to be consulted, the commit object does not need to be inflated, and the contents of the commit object do not need to be parsed.
