[lld] [CMake] Export symbols after `target_link_libraries` for lld (PR #115700)

[via llvm-commits]

https://github.com/shatyuka created https://github.com/llvm/llvm-project/pull/115700

Found that lld only exports very few symbols after enable `LLVM_EXPORT_SYMBOLS_FOR_PLUGINS`.

We need to collect `LINK_LIBRARIES` after all `target_link_libraries` calls.
