Unrolled build for rust-lang#118781

Rollup merge of rust-lang#118781 - RalfJung:core-panic-feature, r=the8472 merge core_panic feature into panic_internals I don't know why those are two separate features, but it does not seem intentional. This merge is useful because with rust-lang#118123, panic_internals is recognized as an internal feature, but core_panic is not -- but core_panic definitely should be internal.
