Fix #14674: Enable overriding "pythonPath" in the launcher
Fix #12462: Update launch.json schema to add "python" and remove "pythonPath" Split the "pythonPath" debug property into "python", "debugAdapterPython", and "debugLauncherPython". Do most debug config validation on fully expanded property values via resolveDebugConfigurationWithSubstitutedVariables(). Add fixups for legacy launch.json with "pythonPath".
