Rework EffectCombiner into ECS

[Helco]

After going back and forth about whether EffectCombiner and their parts should be integrated into ECS (and therefore better use batching) I have decided to quickly try it out and choose later.

Also this turned into another rework of dynamic meshes, as for batch-rendering effect parts I needed partially-resettable vertex buffers and custom index buffers. However this should also allow us to again use a single instance buffer across all ModelRenderer

Result so far: Although there might be edge cases hiding in probably something like ElectricBolt or ParticleEmitter and I am not sure that I implemented the sparks renderer correctly I will merge this as is and setup a group issue to track the remaining combiner parts to implement.
(Also beam effects and game-controlled progress)
With MovingPlanes and RandomPlanes implemented (fully) this accounts for 43% of combiner parts.
