We validate the *format* of email addresses in many places with a match against a regex, often with very slightly different syntax. Adding a separate EmailAddressValidator simplifies the code in a few spots and feels cleaner. Deprecated the old location in case someone is using it in a plugin. No functionality change is in this commit. Note: the regex used at the moment does not support using address literals, e.g.: * localpart@[192.168.0.1] * localpart@[2001:db8::1]
