[lldb/Interpreter] Add ScriptInterpreter Wrapper for ScriptedProcess

This patch adds a ScriptedProcess interface to the ScriptInterpreter and
more specifically, to the ScriptInterpreterPython.

This interface will be used in the C++ `ScriptProcess` Process Plugin to
call the script methods.

At the moment, not all methods are implemented, they will upstreamed in
upcoming patches.

This patch also adds helper methods to the ScriptInterpreter to
convert `SBAPI` Types (SBData & SBError) to `lldb_private` types
(DataExtractor & Status).
