Improve diagnostics for `concat_bytes!` with C string literals
Use the same error as other invalid types for `concat_bytes!`, rather than using `ConcatCStrLit` from `concat!`. Also add more information with a note about why this doesn't work, and a suggestion to use a null-terminated byte string instead.
