Can't use `unsafe` in bsn expression

[Freyja-moth]

Bevy version and features

main

What you did

#[derive(Component, Clone)]
pub struct Value(NonZeroU8);

impl Default for Value {
    fn default() -> Self {
        Self(unsafe { NonZeroU8::new_unchecked(1) })
    }
}

fn value() -> impl Scene {
    bsn! {
        Value(unsafe { NonZeroU8::new_unchecked(4) })
    }
}

What went wrong

error: Unexpected input: Invalid BsnValue. This does not match any expected BSN value type.

If unsafe blocks are supported, const and async (move) blocks should probably be supported as well
