object-file: hide internals when we need to reprepare loose sources
There are two different situations where we have to clear the cache of
loose objects:
- When freeing the loose object source itself to avoid memory leaks.
- When repreparing the loose object source so that any potentially-
stale data is getting evicted from the cache.
The former is already handled by `odb_source_loose_free()`. But the
latter case is still done manually by in `odb_reprepare()`, so we are
leaking internals into that code.
Introduce a new `odb_source_loose_reprepare()` function as an equivalent
to `packfile_store_prepare()` to hide these implementation details.
Furthermore, while at it, rename the function `odb_clear_loose_cache()`
to `odb_source_loose_clear()`.
