Add VisitEntities for generic and reflectable Entity iteration (#15425)
# Objective

- Provide a generic and _reflectable_ way to iterate over contained
entities

## Solution

Adds two new traits:

* `VisitEntities`: Reflectable iteration, accepts a closure rather than
producing an iterator. Implemented by default for `IntoIterator`
implementing types. A proc macro is also provided.
* A `Mut` variant of the above. Its derive macro uses the same field
attribute to avoid repetition.

## Testing

Added a test for `VisitEntities` that also transitively tests its derive
macro as well as the default `MapEntities` impl.
