object-name: introduce `repo_get_oid_with_flags()`

Introduce a new function `repo_get_oid_with_flags()`. This function
behaves the same as `repo_get_oid()`, except that it takes an extra
`flags` parameter that it ends up passing to `get_oid_with_context()`.

This function will be used in a subsequent commit.
