Error info has been added to LoadState::Failed (#12709)

Browse source 
# Objective

Fixes #12667.

## Solution

- Stored
[AssetLoadError](https://docs.rs/bevy/latest/bevy/asset/enum.AssetLoadError.html)
inside of
[LoadState::Failed](https://docs.rs/bevy/latest/bevy/asset/enum.LoadState.html)
as a Box<AssetLoadError> to avoid bloating the size of all variants of
LoadState.
- Fixed dependent code

## Migration guide

Added
[AssetLoadError](https://docs.rs/bevy/latest/bevy/asset/enum.AssetLoadError.html)
to
[LoadState::Failed](https://docs.rs/bevy/latest/bevy/asset/enum.LoadState.html)
option
Removed `Copy`, `Ord` and `PartialOrd` implementations for
[LoadState](https://docs.rs/bevy/latest/bevy/asset/enum.LoadState.html)
enum
Added `Eq` and `PartialEq` implementations for
[MissingAssetSourceError](https://docs.rs/bevy/latest/bevy/asset/io/struct.MissingAssetSourceError.html),
[MissingProcessedAssetReaderError](https://docs.rs/bevy/latest/bevy/asset/io/struct.MissingProcessedAssetReaderError.html),
[DeserializeMetaError](https://docs.rs/bevy/latest/bevy/asset/enum.DeserializeMetaError.html),
[LoadState](https://docs.rs/bevy/latest/bevy/asset/enum.LoadState.html),
[AssetLoadError](https://docs.rs/bevy/latest/bevy/asset/enum.AssetLoadError.html),
[MissingAssetLoaderForTypeNameError](https://docs.rs/bevy/latest/bevy/asset/struct.MissingAssetLoaderForTypeNameError.html)
and
[MissingAssetLoaderForTypeIdError](https://docs.rs/bevy/latest/bevy/asset/struct.MissingAssetLoaderForTypeIdError.html)
