Add the ability to create action types/actions in only Rust; correctly write actions in Android

[Innominus]

Code formatter has changed the kt code structure for the edited file. If it's not following guidelines/code format standards I'm happy to remove the extra whitespace changes.

Essentially it seems when writing the actions for an action group, it wasn't writing them the same way it was reading them. So it would add the actions but without an ID/title/input so they would show up blank.

Before:

After:

This is also what the code might look like when using the new builder syntax for ActionType and Action:

    let action_type = ActionType::builder("action-buttons")
        .actions(vec![
            Action::builder("visible-id", "Visible").foreground(true).build(),
            Action::builder("notification-action-id", "Notification Action Titles")
                .foreground(true)
                .build(),
        ])
        .build();
