Change `bytes!()` to return { static BYTES: &'static [u8] = &[...]; BYTES } This gives it the `'static` lifetime, whereas before it had an rvalue lifetime. Until recently this would have prevented assigning `bytes!()` to a static, as in static FOO: &'static [u8] = bytes!(1,2,3); but #14183 fixed it so blocks are now allowed in constant expressions (with restrictions). Fixes #11641.
