refactor: lake: introduce LogConfig (#10468)
This PR refactors the Lake log monads to take a `LogConfig` structure
when run (rather than multiple arguments). This breaking change should
help minimize future breakages due to changes in configurations options.

In addition, the CLI logging monad stack has been polished up and
`LogIO` now supports the `failLv` configuration option.
