Call target_link_options_shared_lib in executorch-config.cmake (#12320)

Customers need the flags this sets (`--whole-archive` or `-force_load`),

Testing: ~~I'm not sure that we have automated coverage for this file,
so I'm sending a first version adding an intentional break.~~ We have
automated coverage for this file.
