CMake: Clean up dumpcodemodel build system code

Don't depend on apiextractor_SOURCE_DIR to get the apiextractor
include paths, in the future the tests might not be built
as part of the apiextractor project, thus the variable would be empty.
Instead use an explicit path to the directory.

Don't publicly link against apiextractor and Core, PUBLIC usage
requirements don't make sense for executables.

Pick-to: 6.2
