Depend on bevy_tasks::block_on instead of futures_lite::block_on (#20495)

# Objective
`bevy_tasks::block_on` is aliased depending on the features enabled on
the crate. If a Bevy-specific version of a `block_on` is implemented, it
should be using it as well. The rest of the engine should use the
version bevy_tasks exposes.

## Solution
Remove the direct dependencies on `futures_lite::block_on` and use
`bevy_tasks::block_on` instead.

## Testing
CI should pass.
