Expire artifacts before deleting them physically (#29241)

https://github.com/go-gitea/gitea/pull/27172#discussion_r1493735466

When cleanup artifacts, it removes storage first. If storage is not
exist (maybe delete manually), it gets error and continue loop. It makes
a dead loop if there are a lot pending but non-existing artifacts.

Now it updates db record at first to avoid keep a lot of pending status
artifacts.
