[chiselsim] Change HasCliSimulator package

Move the HasCliSimulator trait from the `testing.scalatest` package to the
`simulator.scalatest` package.  This could technically go in either
location as it depends on `HasConfigMap`.  However, because it is
clearly has to do with simulation, I moved it.
