multithread: refactor update thread, communication between mesh/gen/upd threads
...
- Use parallel_for to iterate over all the stored chunks
- Only push a chunk to a queue if it is not already present, using chunk state bitfield (solves
memory leak, continously adding new elements to a queue)
- Properly delete an element from chunks concurrent_hash_map using accessor, then free the memory
(solves memory leak: not being able to delete old elements and always adding new ones)
Breaks:
- Rendering (will be properly refactored in a future commit)
- Block picking (will be refactored in a future commit)

Returning Block::AIR when chunk is not yet generated (CHUNK_STATE_GENERATED set to false) is also a way to avoid thread-unsafe concurrent

generating the Chunk and set again to true after generation is complete
