When a "normal" target (e.g., an executable) depends on a custom target
that is not part of `all`, and that custom target owns the output of a
custom command marked `CODEGEN`, an explicit `add_dependencies` from
the normal to custom target must be incorporated in `codegen`.
Amends commit 197cb419d1 (add_custom_command: Add CODEGEN support,
2024-05-27, v3.31.0-rc1~394^2), which already incorporated such logic
in the Unix Makefile generator, but was not tested nor implemented for
Ninja.
Fixes: #28092
