`SimulationUtilities::analyze()`: apply accelerations from Moco implicit mode solutions to model

[nickbianco]

We need to apply the acceleration variables from an implicit dynamics solution in Moco to the model when computing quantities in SimulationUtilities::analyze().

This should be similar to how we apply discrete variables to the state for variables for models with implicit auxiliary dynamics.

For this we need to grab the AccelerationMotion from the model and call setUDot():
