This is the second part of a multi-part change to define additional subcommands to the `llvm-xray` tool. This change defines a conversion subcommand to take XRay log files, and turns them from one format to another (binary or YAML). This currently only supports the first version of the log file format, defined in the compiler-rt runtime. Depends on D21987.
