repo: add path.grafts with absolute and relative suffixes 

The repository grafts file specifies alternate parent relationships for
commits and may be used by repository tooling that needs to inspect or
manage grafts. Scripts currently retrieve its location by invoking
`git rev-parse --git-path info/grafts`.

Introduce `path.grafts.absolute` and `path.grafts.relative` keys to
`git repo info`. This exposes the grafts file location as a scriptable
config-like key using standard format rules, allowing scripts to
retrieve it through the same interface as other repository path
information.
