Downloader: add ProhibitNewDownloads() (#8939)
"whitelisting" mechanism (list of files - stored in DB) - which
protecting us from downloading new files after upgrade/downgrade was
broken. And seems it became over-complicated with time.
I replacing it by 1 persistent flag inside downloader:
"prohibit_new_downloads.lock"
Erigon will turn downloader into this mode after
downloading/verification of first snapshots.


```
//Corner cases:
	// - Erigon generated file X with hash H1. User upgraded Erigon. New version has preverified file X with hash H2. Must ignore H2 (don't send to Downloader)
	// - Erigon "download once": means restart/upgrade/downgrade must not download files (and will be fast)
	// - After "download once" - Erigon will produce and seed new files
```

------
`downloader --seedbox` is never "prohibit new downloads"
