Fresh-synced history expiry node has high static until restart

Describe the bug

A Reth node synced with history expiry will have a static directory of around 726GB in size.

After a restart of Erigon, it deletes the historic blocks and static is around 443GB.

Arguably, Reth should delete static without restart, after it is “done” with that static file - whenever that is in the sync process.

Steps to reproduce

Sync a Reth node with history expiry, do not restart.

Observe size of static directory

Restart Reth

Observe size of static directory
