fix for [#36260] 2,300 Objects Makes Blender Unresponsive
- performance of outliner was low because of unoptimal data structures.
- now it uses BLI_mempool instead of custom mempool and GHash to make searches for duplicates faster.
- also fix undesired behaviour of BLI_mempool_as_arrayN
thanks to Campbell Barton and Lukas Tönne for helping me get a better fix put together.
