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

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.
