bevy_image: derive TypePath when Reflect is not available (#18501)
# Objective

- bevy_image fails to build without default features:

```
- `Asset` trait depends on `TypePath` which is in bevy_reflect. it's
usually implemented by the `Reflect` derive


## Solution

- make bevy_reflect not an optional dependency
- when feature `bevy_reflect` is not enabled, derive `TypePath` directly
