[Enhancement]: Defer the unlink operation until after munmap #41636

What would you like to be added?
In our current approach, to bind the file object with the process lifecycle, we unlink the file immediately after mmap. This makes the file invisible to the file system and hinders precise disk usage tracking. It is advisable to defer the unlink operation until after munmap.
When a segment object or index is destroyed, we execute munmap, unlink(filepath), and close(fd). Even if these operations fail, we depend on startup cleanup or hook-based cleanup as a fallback.
Why is this needed?
