[MAPS3D-1719] Fix occlusion queries (#5486)

Address Adreno issues, which are seen as constant OpenGL error spamming when occlusion query count goes beyond a certain limit.

* limit number of OpenGL query objects
* introduce a delay between query finish and results retrieval
* issue occlusion queries via priority queue
  * remove occlusion query from queue to prevent stall queries
  * priorities work in a fifo order
* use plf_list as container, same guarantees as `std::list` but less allocations
* Modify occlusion fade: use constant acceleration fade to reduce flickering
