Gets rid of the largest set of mutable global state within the core. This also paves a way for eliminating usages of GetInstance() on the System class as a follow-up. Note that no behavioral changes have been made, and this simply extracts the functionality into a class. This also has the benefit of making dependencies on the core timing functionality explicit within the relevant interfaces.
