Alexandru Croitor 04d895681a CMake: Fix creation of versionless targets for tools
We can't use qt_internal_export_modern_cmake_config_targets_file for
executables like tools, because it's not possible to use
INTERFACE_LINK_LIBRARIES with executables like you can with libraries.
We also can't create aliases to non-global imported targets.

Instead create new imported executable targets, fish out the imported
location, and assign it to the versionless targets.
