fix tidy errors

- line wrapping
- extend the mapping of target_arch to llvm_component in tidy itself so it can
  handle target tuples that start with an aarch64v8r component
- fix needs-llvm-component directive in `aarch64v8r` UI assembly test
- extend `tests/assembly-llvm/targets/targets-elf.rs` as per target policy check
