[CMake] Utils.cmake, function name kernel_link_options() and target_link_options_shared_lib() misleading

[kirklandsign]

🐛 Describe the bug

Seems that kernel_link_options really means whole-archive (keeping all symbols, don't prune due to no direct usage!) and target_link_options_shared_lib() is a wrapper for kernel_link_options().

Note that this is not accurate. For kernel, we need to whole-archive to prevent from missing symbol. For shared lib, most likely, we need to keep symbols, but not necessarily all of them (can depend on other dylib definition).

My suggestion is change the name a bit, like "link_options_whole".

Also would love to have some tool, to check if there is any duplicated symbol in our .a. And also .so.
