In this patch we split the serialization routine into two different routines: `getCLIOptionsValues()` for only serializing the key-value pairs and `getCLIOptionsInfo()` for getting additional information such as help text etc. The former is used a lot more frequently than the latter, which is only used for generating `--help` and building `process.allowedNodeEnvironmentFlags`. `getCLIOptionsValues()` also adds `--no-` entries for boolean options so there is no need to special case in the JS land. This patch also refactors the option serialization routines to use v8::Object constructor that takes key-value pairs in one go to avoid calling Map::Set or Object::Set repeatedly which can go up to a patched prototype.
