Particle: optimize threading for many particles and many cores

The maximum particles per task of 256 was outdated and lead to too much thread
contention. Instead define a low fixed number of tasks per thread.

On a i7-7700HQ, creating 4 million particles went down from 31s to 4s.

Thanks to Oscar Abad, Sav Martin, Zebus3d, Sebastin Barschkis and Martin Felke
for testing and advice.
