[core] Switch from background to foreground placement
- Background placement code now just generates static symbol buffers
- Don't render GeometryTiles until their symbols are loaded. This is necessary for the CrossTileSymbolIndex to successfully prevent flicker.
- SymbolInstances are transferred to SymbolBucket for use on foreground during collision detection
- Symbols are sorted on foreground by sorting their index buffer but leaving vertex buffers intact (only works within one segment)
- Vertical glyphs are generated at same time as horizontal glyphs. `reprojectLineLabels` chooses which one to use at render time and hides the other.
- Icons are now always represented with a single collision box, even if they're placed along a line (this means their rotation alignment may be wrong, but the approach of representing them with multiple collision boxes wasn't very accurate either).
- Generate vertices for new debug collision boxes and collision circles
- Only add symbols within tile boundaries (reduces work, avoids double-draw)
- Update symbol_projection.cpp to support line label projection calls from CollisionIndex.
