Allow other plugins to create renderer resources (#9925)
This is a duplicate of #9632, it was created since I forgot to make a
new branch when I first made this PR, so I was having trouble resolving
merge conflicts, meaning I had to rebuild my PR.

# Objective

- Allow other plugins to create the renderer resources. An example of
where this would be required is my [OpenXR
plugin](https://github.com/awtterpip/bevy_openxr)

## Solution

- Changed the bevy RenderPlugin to optionally take precreated render
resources instead of a configuration.

## Migration Guide

The `RenderPlugin` now takes a `RenderCreation` enum instead of
`WgpuSettings`. `RenderSettings::default()` returns
`RenderSettings::Automatic(WgpuSettings::default())`. `RenderSettings`
also implements `From<WgpuSettings>`.

```rust
// before
RenderPlugin {
    wgpu_settings: WgpuSettings {
    ...
    },
}

// now
RenderPlugin {
    render_creation: RenderCreation::Automatic(WgpuSettings {
    ...
    }),
}
// or
RenderPlugin {
    render_creation: WgpuSettings {
    ...
    }.into(),
}
```
