[Feat] Add support for MapLibre Tile (MLT) format

### Target Use Case

This was recently announced and sounds like it has some nice improvements over MVT: https://maplibre.org/news/2026-01-23-mlt-release/

### Proposal

Not sure if we need a new MLTLayer component or if this can just be handled by the existing MVTLayer and new loader.gl code, but I thought I'd create this ticket to start the discussion
