Hi,

To simplify code for new access types [1], add 2 new helpers:
- landlock_union_access_masks()
- landlock_get_applicable_domain()

This fourth version mainly rename these helpers.

The last patch uses these helpers to optimize Landlock scope management
like with filesystem and network access checks.

Previous version:
v3: https://lore.kernel.org/r/20241022151144.872797-2-mic@digikod.net
v2: https://lore.kernel.org/r/20241014124835.1152246-1-mic@digikod.net
