Blueprints Rework (#18947)

Reworks blueprints to use an eye component for area selection and
changing. Blueprints will now work on whichever overmap site they spawn
on if overmap is enabled, though currently they have only been added to
the Horizon.

Adds shuttle-modifying blueprints for altering shuttle areas and
exoplanet outpost blueprints for creating areas on exoplanets. A set of
outpost blueprints and a lockbox containing blueprints for the Horizon's
shuttles have been added to the CE's locker.

Moves eye creation to a component.
