core/rawdb: find smallest block stored in key-value store when chain gapped (#26719)

Browse Source 
This change prints out more information about the problem, in the case where geth detects a gap between leveldb and ancients, so we can determine more exactly where the gap is (what the first missing is). Also prints out more metadata.
