refactor(sim/compute): Simplify SimHypervisor class

This change simplifies the SimHypervisor class into a single
implementation. Previously, it was implemented as an abstract class with
multiple implementations for each multiplexer type. We now pass the
multiplexer type as parameter to the SimHypervisor constructor.
