Rename timestamp module to time

We just re-named `Timestamp` to `BlockTime`. We have a `units::block`
module but it currently holds abstractions (`BlockHeight` and
`BlockInterval`) that are not onchain abstractions and therefore
somewhat different from the `BlockTime`. Instead of making `block` a
block 'utils' module instead re-name the `timestamp` module to `time`.
