retpoline and retpoline-external-thunk flags (target modifiers) to enable retpoline-related target features `-Zretpoline` and `-Zretpoline-external-thunk` flags are target modifiers (tracked to be equal in linked crates). * Enables target features for `-Zretpoline-external-thunk`: `+retpoline-external-thunk`, `+retpoline-indirect-branches`, `+retpoline-indirect-calls`. * Enables target features for `-Zretpoline`: `+retpoline-indirect-branches`, `+retpoline-indirect-calls`. It corresponds to clang -mretpoline & -mretpoline-external-thunk flags. Also this PR forbids to specify those target features manually (warning). Issue: rust-lang/rust#116852
