object: clear grafts when clearing parsed object pool

Browse Source 
We do not clear grafts part of the parsed object pool when clearing the
pool itself, which can lead to memory leaks when a repository is being
cleared.

Fix this by moving `reset_commit_grafts()` into "object.c" and making it
part of the `struct parsed_object_pool` interface such that we can call
it from `parsed_object_pool_clear()`. Adapt `parsed_object_pool_new()`
to take and store a reference to its owning repository, which is needed
by `unparse_commit()`.
