Improve spatial visualization performance

[oscarlorentzon]

Motivation

Make spatial visualization responsive for up to ~10k cameras in view

Contribution

• Logarithmic raycasting complexity through Octree structure for cameras
• Linear camera frame render complexity improved through less objects, less render calls, and less matrix updates
• Add spatial intersect API to raycast camera frames
• Rename spatial configuration tilesVisible property to cellsVisible
• Add spatial configuration cell grid depth property
