Autogen: Add (CMAKE_)AUTOGEN_ORIGIN_DEPENDS support

This adds

- the variable ``CMAKE_AUTOGEN_ORIGIN_DEPENDS`` which initializes
- the target property ``AUTOGEN_ORIGIN_DEPENDS``

which controls whether or not the origin target dependencies
should be forwarded to the corresponding ``_autogen`` target.

The default value of ``CMAKE_AUTOGEN_ORIGIN_DEPENDS`` is ``ON``
which corresponds to the behavior that is in place since CMake 3.9.

Closes: #18493
