src: enable context snapshot after running per-context scripts
At build time, snapshot the context after running per-context scripts in the main instance, and in the final build, deserialize the context in the main instance. This provides a ~5% in the misc/startup benchmark when the instance is launched within a process that runs test/fixtures/semicolon.js.
