bmeurer 23ac686ff8 [types] Use the TypeCache consistently for common types. 
Rename ZoneTypeCache to TypeCache and use a single shared (immutable)
instance consistently to cache the most commonly used types. Also serves
as a chokepoint for defining those types, so we don't repeat the
definition (and possible bugs) in various places.
