Update docs following LLVM AOT linker cleanup. (#4950)
Redo of https://github.com/google/iree/pull/4761 after GitHub silliness.
Note that the `docs/get_started/getting_started_riscv_cmake.md` changes slightly overlap with https://github.com/google/iree/pull/4940.
Fixes https://github.com/google/iree/issues/4606 (now that https://github.com/google/iree/pull/4719 is also merged)
