Reduce use of SuperParticle

[AlexanderSinn]

Summary

In preparation of #4404, this PR reduces the reliance of SuperParticle. The issue with getSuperParticle is that the compiler is instructed to read in all the data of the particle into registers even if most of it is not needed. Additionally, runtime data is not accessible through SuperParticle.
