From: Xing Xin <xingxin.xx@bytedance.com>

Currently, we can use "transfer.fsckObjects" and the more specific
"fetch.fsckObjects" to control checks for broken objects in received
packs during fetches. However, these configurations were only
acknowledged by `fetch-pack.c:get_pack` and did not take effect in
direct bundle fetches or fetches with _bundle-uri_ enabled.

This commit exposes the fetch-then-transfer configuration logic by
adding a new function `fetch_pack_fsck_objects` in fetch-pack.h. This
new function is used to replace the assignment for `fsck_objects` in
`fetch-pack.c:get_pack`. In the next commit, this function will also be
used to extend fsck support for bundle-involved fetches.
