[PATCH v2 1/7] builtin/repo: group per-type object values into struct

[Justin Tobler <jltobler@gmail.com>]

The `object_stats` structure stores object counts by type. In a
subsequent commit, additional per-type object measurements will also be
stored. Group per-type object values into a new struct to allow better
reuse.
