bevy_dylib: Apply #![warn(clippy::allow_attributes, clippy::allow_attributes_without_reason)] (#17332)

# Objective
- https://github.com/bevyengine/bevy/issues/17111

## Solution
Set the `clippy::allow_attributes` and
`clippy::allow_attributes_without_reason` lints to `warn`, and bring
`bevy_dylib` in line with the new restrictions.

## Testing
`cargo clippy --tests --all-features --package bevy_dylib` was run, and
no warnings were encountered.

I would've skipped over this crate if there weren't the two lint
attributes in it - might as well handle it now, y'know?
