core: pass block into collectLogs (#26335) 

While investigating another issue, I found that all callers of collectLogs have the
complete block available. rawdb.ReadReceipts loads the block from the database,
so it is better to use ReadRawReceipts here, and derive the receipt information using
the block which is already in memory.
