Currently, the toolchain CMake files use the remove_duplicated_flags function from utilities.cmake. The cmakev2 implementation also includes this function for backward compatibility. Move the remove_duplicated_flags function to a separate file, deduplicate_flags.cmake, so it can be shared between cmakev1 and cmakev2.
