Static physics for Frontier grids

[whatston3]

About the PR

Sets most Frontier stations and POI grids to static bodies.

Adds a new component, ForceAnchorComponent, that, when placed on an entity that initializes, sets the physics status of the entity to Static and OnGround. This results in easier physical simulation. It also adds another new component, PreventGridAnchorChangesComponent, which prevents station anchors from changing a grid's anchored status.

Why / Balance

Physics bad. Less physics good.

Should result in less unpredictable jank through massive physics parameters (ships getting massive impulses when bonking the station slightly)

How to test

1. Spawn in-game.
2. Check the PhysicsComponent on Frontier Outpost. It should be OnGround and Static. Check the ShuttleComponent, it should be disabled.
3. Check the PhysicsComponent on the NFSD Outpost. It should be OnGround and Static. Check the ShuttleComponent, it should be disabled.
4. Run addgamerule BluespaceCave. Wait for the cave to appear.
5. Check the PhysicsComponent on the Cave, it should be OnGround and Static. Check the ShuttleComponent, it should be disabled.
6. Add a station anchor [On] to the cave. Turn it off. Check the Physics and ShuttleComponents on the Cave, there should be no changes.
7. Repeat step 6 for the Frontier Outpost.
8. Repeat step 6 for the NFSD Outpost.
9. Purchase a Pioneer at Frontier Outpost.
10. Repeat step 6 for the pioneer. When the station anchor is on, it should be immobile, and when it is off, it should be able to move.
11. Repeat step 6 on the Public Transit Shuttle, then turn it back on. The shuttle should remain InAir and Dynamic regardless of the anchor's state.

• fix: Immobile stations should have fewer issues with physics simulation.

Should be good.
