Joe Tsai e4fcb9f7e7 reflect: add protopath and protorange packages
The protopath package provides a means to programmatically represent
a sequence of protobuf reflection operations.
The protorange package traverses through a message and
calls a user-provided function as it iterates.

This feature sets the groundwork for the often requested feature
of being able to exclude certain fields when merging or serializing.

package protopath

    type Step struct{ ... }

        func AnyExpand(protoreflect.MessageDescriptor) Step
        func (Step) Kind() StepKind
        func (Step) FieldDescriptor() protoreflect.FieldDescriptor
        func (Step) MessageDescriptor() protoreflect.MessageDescriptor
        func (Step) ListIndex() int
        func (Step) MapIndex() protoreflect.MapKey
        func (Step) String() string
    type StepKind int

        Values []protoreflect.Value
    }
    func (Values) Index(int) (out struct{ ... })
    func (Values) Len() int
    func (Values) String() string

package protorange
