Fix 'unknown option --no-undefined' linker error in cmake script (OS X)

Use check_linker_flag() and LINKER prefix in CMakeLists.txt.
This fixes the linker error that "--no-undefined" option is unknown,
at least with apple-clang 13.0.

* CMakeLists.txt [CMP0057] (CMP0057): Set to NEW.
* CMakeLists.txt [$CMAKE_VERSION<3.18.0]: Include CheckLinkerFlag.
* CMakeLists.txt [BUILD_SHARED_LIBS] (WL_NO_UNDEFINED_OPT): New
variable.
* CMakeLists.txt [BUILD_SHARED_LIBS && $CMAKE_VERSION>=3.18.0]
(WL_NO_UNDEFINED_OPT): Use "LINKER:" prefix.
* CMakeLists.txt [BUILD_SHARED_LIBS && $CMAKE_VERSION>=3.18.0]
(HAVE_FLAG_WL_NO_UNDEFINED): Use check_linker_flag(C) instead of
check_c_compiler_flag.
* CMakeLists.txt [BUILD_SHARED_LIBS && $CMAKE_VERSION<3.13.0] (gc,
gccpp, gctba, cord): Use $WL_NO_UNDEFINED_OPT.
* CMakeLists.txt [BUILD_SHARED_LIBS && $CMAKE_VERSION>=3.13.0] (gc,
gccpp, gctba, cord): Use target_link_options instead of
target_link_libraries; remove TODO item.
