rust-repo: make `Send` by not storing functions in `LazyCell`

We (Google) want to use `Repo` in a context where we can store it in
`Mutex<Repo>`. However, that currently doesn't work because it's not
`Send` because the `LazyCell` initialization functions are not
`Send`. It's easy to fix that by passing them to the `get_or_init()`
and `get_mut_or_init()` functions. We'll probably also want `Repo` to
be `Send` (and even `Sync`) in core later, so this seems like a step
in the right direction.
