Autogen: Add support for global ``autogen`` and ``autorcc`` targets

This teaches CMake the variables

- CMAKE_GLOBAL_AUTOGEN_TARGET
- CMAKE_GLOBAL_AUTOGEN_TARGET_NAME
- CMAKE_GLOBAL_AUTORCC_TARGET
- CMAKE_GLOBAL_AUTORCC_TARGET_NAME

which control the generation of global
``autogen`` and ``autorcc`` targets.

Closes #17721
