fix: disable Qt versionless targets to silence IMPORTED_LOCATION codemodel errors

Conan ships the Qt host tools as a single RelWithDebInfo config, so the versionless Qt:: tool targets only carry a config-less IMPORTED_LOCATION. On non-Release builds the IDE CMake file-API codemodel then reports "IMPORTED_LOCATION not set ... configuration <cfg>" for each of them. The project already references Qt solely through the versioned Qt6:: targets, so suppress the versionless aliases entirely via QT_NO_CREATE_VERSIONLESS_TARGETS.
