  -----------
  lld/cmake: Drop use of llvm-config for LLVM install discovery

This has been deprecated since D116492 earlier in 2022.

That seems recent, but with the recent cut of LLVM 15 that is still two releases (14 and 15). Meanwhile Clang has deprecated `llvm-config` for a lot longer, and since it is likely that LLD users are also Clang users, this serves as an extra "heads up" that `llvm-config` is on its way out.

Remove it in favor of using CMake's find_package() function.
