1. Introduce optional global TypeInfoCache …

   In the current implementation, `TypeInfoCache` is a per-connection
   cache. This means, over time, that the same type information is
   retrieved from the database copious times. For some DB systems, this
   has a negative cost/performance impact.
   
   Introduce an optional global `TypeInfoCache`. This is useful for
   cases where a single DB system is used in Production for all
   connections and there's no need for each connection to re-retrieve
   type info.
   
   - Extract the storage portion of `TypeInfoCache` into a new class,
   `TypeInfoCacheStorage`
   - Add new property, `GLOBAL_TYPE_INFO_CACHE` to enable a global cache
   - When enabled, the constant `TypeInfoCacheStorage GLOBAL_INSTANCE` is
   always used. Over the course of running a Production instance, this global
   cache should not need to query the database for type info.
