Have EntityCommands methods consume self for easier chaining (#14897)

Browse source 
# Objective

Fixes #14883

## Solution

Pretty simple update to `EntityCommands` methods to consume `self` and
return it rather than taking `&mut self`. The things probably worth
noting:

* I added `#[allow(clippy::should_implement_trait)]` to the `add` method
because it causes a linting conflict with `std::ops::Add`.
* `despawn` and `log_components` now return `Self`. I'm not sure if
that's exactly the desired behavior so I'm happy to adjust if that seems
wrong.

## Testing

Tested with `cargo run -p ci`. I think that should be sufficient to call
things good.

## Migration Guide

The most likely migration needed is changing code from this:

```
        let mut entity = commands.get_or_spawn(entity);

        if depth_prepass {
            entity.insert(DepthPrepass);
        }
        if normal_prepass {
            entity.insert(NormalPrepass);
        }
        if motion_vector_prepass {
            entity.insert(MotionVectorPrepass);
        }
        if deferred_prepass {
            entity.insert(DeferredPrepass);
        }
```

to this:

```
        let mut entity = commands.get_or_spawn(entity);

        if depth_prepass {
            entity = entity.insert(DepthPrepass);
        }
        if normal_prepass {
            entity = entity.insert(NormalPrepass);
        }
        if motion_vector_prepass {
            entity = entity.insert(MotionVectorPrepass);
        }
        if deferred_prepass {
            entity.insert(DeferredPrepass);
        }
```

as can be seen in several of the example code updates here. There will
probably also be instances where mutable `EntityCommands` vars no longer
need to be mutable.
