D12365: import-checker: allow symbol imports from typing module

REVISION SUMMARY
  As we add typing annotations, we'll want to use a lot of symbols from
  the `typing` module. Typing `typing` all the time will be annoying. Let's
  allow symbol imports from this module.
  
  While I was here, I changed some comments from "whitelist" to "allow list"
  as the former is non-inclusive terminology.
