Previously embedded interpreters were handled as ad-hoc source files compiled into source/Interpreter. This made it hard to disable a specific interpreter, or to add support for other interpreters and allow the developer to choose which interpreter(s) were enabled for a particular build. This patch converts script interpreters over to a plugin-based system. Script interpreters now live in source/Plugins/ScriptInterpreter, and the canonical LLDB interpreter, ScriptInterpreterPython, is moved there as well. Any new code interfacing with the Python C API must live in this location from here on out. Additionally, generic code should never need to reference or make assumptions about the presence of a specific interpreter going forward.
