Make toggle method accept impl Into<Option<bool>> (#3446)

This PR makes the `toggle` method on the various list components accept
an `impl Into<Option<bool>>` instead of just an `Option<bool>`.

This allows a caller with just a `bool` avoid having to wrap the
`Option` themselves.

Release Notes:

- N/A
