Cloning into and clone and spawn methods don't cover the same areas

[Freyja-moth]

What problem does this solve or what need does it fill?

Currently when trying to clone components into an existing entity the methods available are

commands.entity(entity)
    .clone_components::<Bundle>(other_entity) 
    .clone_with_opt_in(other_entity, |_| {})
    .clone_with_opt_out(other_entity, |_| {});

However when trying to clone components into a new entity the methods available are

commands.entity(entity)
    .clone_and_spawn()
    .clone_and_spawn_with_opt_in(|_| {})
    .clone_and_spawn_with_opt_out(|_| {});

Cloning components into an already existing is missing an equivalent to clone_and_spawn, and spawning a new entity and cloning components into it is missing an equivalent to clone_components.

What solution would you like?

Change clone_components to clone all components and add a clone_bundle that only clones the components in the bundle.

Add a clone_bundle_and_spawn method for spawning an entity with the cloned components in the bundle.

What alternative(s) have you considered?

Use the already existing clone_(and_spawn)_with_opt_* methods to cover the missing space, however these methods are quite low level and may be confusing for newcomers
