Replace the (class_name, args_sp) parameter pair on CreatePluginObject across the scripted plugin interfaces (ScriptedThread, OperatingSystem, ScriptedBreakpoint, ScriptedFrameProvider, ScriptedProcess, and the underlying ScriptedPythonInterface template) with a single `const ScriptedMetadata &`. Callers (OperatingSystemPython, ScriptedThread, ScriptedProcess, BreakpointResolverScripted, ScriptedFrameProvider) pass their existing ScriptedMetadata directly, removing the need to re-bundle class_name and args at every call site. ScriptedBreakpoint, ScriptedFrameProvider and ScriptedProcess no longer carry a redundant `args_sp` parameter; their callers fold those args into the metadata, and the Python overrides reconstruct a StructuredDataImpl from the metadata's args dict for the dispatched call. ScriptedInterface gains an `m_scripted_metadata` member and a `GetScriptedMetadata()` accessor; ScriptedPythonInterface populates it when CreatePluginObject is invoked so subclasses can later report which script class is in play. Hook/StopHook/ThreadPlan public interfaces keep their existing `args_sp` parameter for now; subsequent commits consolidate that. Signed-off-by: Med Ismail Bennani <ismail@bennani.ma>
