[LTP] [PATCH v3 2/3] tst_atomic: Introduce tst_atomic_t and apply it consistently

[Petr Vorel]

Hi Li,

> This patch introduces a new tst_atomic_t typedef (int32_t) to replace
> direct usage of int in atomic operations across the test framework.

> The changes ensure:

> - Consistent 32-bit atomic operations across platforms
> - Clearer intent for variables used in atomic contexts
> - Better maintainability through centralized type definition
> - Fixed declaration consistency in atomic APIs
