…hters to debug its behavior

This commit modifies the existing InteractionRaycast.gd and to a lesser extent the PlayerInteractionComponent.gd.

InteractionRaycast now uses a shapecast when the raycast doesn't hit a valid collider. If the shapecast hits multiple valid colliders it will use a 'hotspot' and judge distances between it and valid colliders to determine which object the player is more likely intending to pick up.

There is a known issue regarding the ShapeCast3D node reference being lost on scene change.

…rryables

- Turned the Interaction Raycast into a packed scene, to keep child node structure consistent. This should fix reference issues with the Enemy using an interaction raycast.
- Updated the player and enemy packed scene to use said interaction raycast packed scene.
- Added the option to turn debug shapes on/off.

- Turn debug shapes off on ready if they're disabled and ensure they don't turn on any point while playing
- Removed a null ref check having to do with the ShapeCast3D not found for enemy interaction raycast on scene change
