KDL3: Fix world access on non-strict open world

[Silvris]

What is this fixing or adding?

There's just been an entire set of rules missing since the initial merge of KDL3 that only causes an issue on a single settings combination. This creates unbeatable worlds by not accounting for logical requirements for stage completion, which would block access to the level's boss.

How was this tested?

Kirby's Dream Land 3:
    strict_bosses: "false"
    open_world: "true"
    ow_boss_requirement: 6

Watched the generated spheres no longer contain all 5 levels by sphere 5.

If this makes graphical changes, please attach screenshots.
