Qt6's standalone module build installs qsb binary but does not generate the Qt6ShaderToolsTools cmake wrapper package needed by cross-compile. Added a Python generator that creates the minimal cmake package files (Config, Targets, Targets-release, Precheck, AdditionalTargetInfo, VersionlessTargets, Dependencies, ConfigVersion) following the exact pattern of Qt6WaylandScannerTools from qtbase host build.
