Password Manager code clean-up.

It contains a number of tiny clean ups:
1.Using range based for
2.Dropping autofill:: namespace in favor of using
3.Using map lookup instead of range based for by map.
4.Old comment removal in password_manager.cc

Wipe out WipeStoreCopyIfOutdated.

Password Manager ignores saving of Chrome sync credentials. But if
accounts.google.com credentials were saved before signing in in Chrome,
they persist. Which may lead to the problem, that after changing
password, saved sync credentials become obsolete. For this reason it
was introduced wiping such credentials if Password Manager found
submission with different password. The problem that it assumes that
Password Manager always correctly detects success of password form
submission on accounts.google.com. That's not true anymore. As result
valid credentials might be removed. In the current setup probability
of this is low, but with other changes it might become much bigger, for
example  https://crbug.com/871191  is example. So it's the time to remove
wiping.

Remove sending sign-in vote in Password Manager.

Password Manager sends crowdsourcing votes for sign-in forms with labeling of fields
 with Autofill votes. The idea to use autofill votes in such situation is deprecated now.
And moreover on the CL https://chromium-review.googlesource.com/c/chromium/src/+/1219710
 it's allowed to send normal Password Manager votes for sign-in forms.

So in order to avoid double vote sending and decrease code complexity it's now time
 to remove sign-in vote sending.
