Rollup merge of #152794 - reddevilmidzy:mgca-print, r=BoxyUwU

Fix ICE in `try_to_raw_bytes` when array elements have mismatched

close: rust-lang/rust#152683

After rust-lang/rust#152001, suffixed integer literals preserve their own type during const lowering, so `try_to_raw_bytes` could call `.to_u8()` on a scalar with size > 1, causing an ICE. Fix by using `try_to_bits(Size::from_bytes(1)).ok()` instead.
