[PATCH v2 i-g-t 1/2] igt_core_get_igt_hook: igt_hook pointer for other libs

[Gustavo Sousa]

Quoting Peter Senna Tschudin (2025-07-13 08:23:53-03:00)
>Previously, all igt_hooks were defined, initialized, and freed within
>lib/igt_core.c, limiting hook creation to this file. To enable other
>libraries to add hooks, introduce a function that returns a pointer to
>the main hook structure.
>
>This change allows hooks to be created from external libraries without
>requiring separate initialization or teardown of the hook
>infrastructure.
