src: port --bash-completion to C++

So that it gets handle earlier and faster during the bootstrap
process.

Drive-by fixes:

- Remove `[has_eval_string]` and `[ssl_openssl_cert_store]` from
  the completion output
- Set `kProfProcess` execution mode for `--prof-process` instead
  of `kPrintBashProcess` which is removed in this patch.
- Append new line to the end of the output of --bash-completion
