Use BevyError for AssetLoader::Error (#19478)

Browse Source 
# Objective

Allow using `BevyResult` in `AssetLoader`s for consistency. Currently,
it converts errors into `Box<dyn core::error::Error + Send + Sync +
'static>`, which is essentially a `BevyError` without the optional
backtrace functionality.

## Solution

I don't think needs a migration guide as any type that satisfies
`Into<Box<dyn core::error::Error + Send + Sync + 'static>>` also
satisfies `Into<BevyError>`.
