Some JSC Options refactoring and enhancements

[Mark Lam]

Create a better encapsulated Option class to make working with options easier.  This is a building block towards a JIT policy scaling debugging option I will introduce later.

This work entails:
1. Convert Options::Option into a public class Option (who works closely with Options).
2. Convert Options::EntryType into an enum class Options::Type and make it public.
3. Renamed Options::OPT_<option name> to Options::<option name>ID because it reads better.
4. Add misc methods to class Option to make it more useable.

FYI, these style violations are intentional and needed to be able to automtically synthesize Options functions via macros.  These warning only surfaced because I moved the Options::EntryType enums into the new Options::Type enums.
