Attach timestamp to various data

[tjayrush]

Timestamp is not always part of the data -- for example chifra trace does not include timestamp (even though it includes block number).

When this code was first written, it would have taken an entire round-trip RPC call to add this data to a trace, but since then, we've implemented the timestamp database which means we can probably attach this data for nearly no cost.

Check other data types (particularly the receipt and log data) because they also probably do not have timestamps.

Timestamps are super useful for filtering by date and would be a good addition to any data.
