cmake: move configure_linker_script to ld/target.cmake
While configure_linker_script() may be useful for other linkers, it currently only aimed at GNU ld. To really be useful among different linkers, we would need to abstract its usage of the C preprocessor. We can do this later, if needed. No functional change expected.
