This patch adds new SBDebugger::GetSetting() API which enables client to access settings as SBStructedData. Implementation wise, a new ToJSON() virtual function is added to OptionValue class so that each concrete child class can override and provides its own JSON representation. This patch aims to define the APIs and implement a common set of OptionValue child classes, leaving the remaining for future patches. This patch is used later by auto deduce source map from source line breakpoint feature for testing generated source map entries. Differential Revision: https://reviews.llvm.org/D133038
