Add a parser for a new "dyndep" file format
Define a file format suitable for specifying dynamically-discovered
dependency information for build edges. Design a format inspired by the
build manifest format and using the same lexer. Start with a required
format version specification followed by "build" statements that add
implicit inputs and outputs to existing edges.
