[PATCH v4 5/7] bulk-checkin: introduce `index_blob_bulk_checkin_incore()`

Now that we have factored out many of the common routines necessary to index a new object into a pack created by the bulk-checkin machinery, we can introduce a variant of `index_blob_bulk_checkin()` that acts on blobs whose contents we can fit in memory.

This will be useful in a couple of more commits in order to provide the `merge-tree` builtin with a mechanism to create a new pack containing any objects it created during the merge, instead of storing those objects individually as loose.

Similar to the existing `index_blob_bulk_checkin()` function, the entrypoint delegates to `deflate_obj_to_pack_incore()`. That function in turn delegates to deflate_obj_to_pack(), which is responsible for formatting the pack header and then deflating the contents into the pack.

Consistent with the rest of the bulk-checkin mechanism, there are no direct tests here. In future commits when we expose this new functionality via the `merge-tree` builtin, we will test it indirectly there.
