core: Support variety of atomic widths in width-agnostic functions Before this change, the following functions and macros were annotated with `#[cfg(target_has_atomic = "8")]` or `#[cfg(target_has_atomic_load_store = "8")]`: * `atomic_int` * `strongest_failure_ordering` * `atomic_swap` * `atomic_add` * `atomic_sub` * `atomic_compare_exchange` * `atomic_compare_exchange_weak` * `atomic_and` * `atomic_nand` * `atomic_or` * `atomic_xor` * `atomic_max` * `atomic_min` * `atomic_umax` * `atomic_umin` However, none of those functions and macros actually depend on 8-bit width and they are needed for all atomic widths (16-bit, 32-bit, 64-bit etc.). Some targets might not support 8-bit atomics (i.e. BPF, if we would enable atomic CAS for it). This change fixes that by removing the `"8"` argument from annotations, which results in accepting the whole variety of widths.
