reflect/protoregistry: initial commit

Package protoregistry provides data structures to register and lookup
protobuf descriptor types.

High-level API:
	var GlobalFiles = new(Files)
	var NotFound = errors.New("not found")
	type Files struct{ ... }
		func NewFiles(...pref.FileDescriptor) *Files
		func (*Files) Register(...pref.FileDescriptor) error
		func (*Files) FindDescriptorByName(pref.FullName) (pref.Descriptor, error)
		func (*Files) RangeFiles(func(pref.FileDescriptor) bool)
		func (*Files) RangeFilesByPackage(pref.FullName, func(pref.FileDescriptor) bool)
		func (*Files) RangeFilesByPath(string, func(pref.FileDescriptor) bool)

To support the FindDescriptorByName method, we add a DescriptorByName to
protoreflect.FileDescriptor and associated logic to prototype.
