Zoxide related features

[chrjabs]

This pull request implements some features related to zoxide:

• Make :z behave more like zoxides z command: in the first place, act like :cd, only if this behaviour fails, query the zoxide database and naviagate to the found match (resolves #240)
• Introduced an opt in feature that updates the zoxide database after every directory change (notably also with manual navigation or :cd). The configuration option is called zoxide_update. (resolves #459)
• Support for arguments passed to the zoxide interactive (:zi) command (resolves #395)
• Support for command aliases with arguments (note: only aliases that do not contain spaces support arguments) (resolves #452)

One question related to the debug assertion introduced here: this is required for the zoxide update to work correctly, but will this always hold? I am confident that this holds when coming from change_directory::change_directory, but the function is also called from open_file::open, where I am not entirely sure.

function is also called from open_file::open, where I am not entirely sure. This one should be fine because its taken from entry.file_path()
