SQLite History MVP with timestamp, duration, working directory, exit status metadata (#5721)

This PR adds support for an SQLite history via nushell/reedline#401

The SQLite history is enabled by setting history_file_format: "sqlite" in config.nu.

* somewhat working sqlite history
* Hook up history command
* Fix error in SQlitebacked with empty lines

When entering an empty line there previously was the "No command run"
error with `SqliteBackedHistory` during addition of the metadata

May be considered a temporary fix
