reflect/protoregistry: add Types registry
The first commit of protoregistry only added a registry for files.
However, a separate type of registry is needed to provide a mapping between
protobuf names and actual Go types representing those names.
Additional high-level API:
var GlobalTypes = new(Types)
type Type interface{ ... }
type Types struct{ ... }
func NewTypes(...Type) *Types
func (*Types) Register(...Type) error
func (*Types) FindEnumByName(pref.FullName) (pref.EnumType, error)
func (*Types) FindMessageByName(pref.FullName) (pref.MessageType, error)
func (*Types) FindMessageByURL(string) (pref.MessageType, error)
func (*Types) FindExtensionByName(pref.FullName) (pref.ExtensionType, error)
func (*Types) FindExtensionByNumber(pref.FullName, pref.FieldNumber) (pref.ExtensionType, error)
func (*Types) RangeEnums(func(pref.EnumType) bool)
func (*Types) RangeMessages(func(pref.MessageType) bool)
func (*Types) RangeExtensions(func(pref.ExtensionType) bool)
func (*Types) RangeExtensionsByMessage(pref.FullName, func(pref.ExtensionType) bool)
