sim: Rename the root stats group to RootStats

Currently, the name of the stats group of thr Root object is
Stats, which is likely to be confused with the Stats namespace.

This commit renames the struct to RootStats. This allows the
Stats namespace to be expressed as `Stats::`, which is
consistent with how the namespace is accessed in other part of
gem5.
