inspector: add a "NodeTracing" domain support
This change adds a new inspector domain for receiving Node tracing data. 1. Node.js now can extend Inspector protocol with new domains with the API defined in the src/inspector/node_protocol.pdl. 2. Plumbing code will be generated at the build time. /json/protocol HTTP endpoint returns both V8 and Node.js inspector protocol. 3. "NodeTracing" domain was introduced. It is based on the Chrome "Tracing" domain.
