Michal Rostecki 474ea87943 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.

Fixes #106845
Fixes #106795
