First step in moving the password autocomplete code from the WebKit API

to the Chromium code.
This is currently behind a #define that will be defined in the WebKit API
when the change is finished on that side.

PasswordAutocompleteManager replaces webpasswordautocompletelistener_impl.cc, it
is responsible for trigering password autocomplete

The unit-tests in webpasswordautocompletelistener_unittest.cc have been ported
to password_autocomplete_manager_unittest.cc. They are now test shell unit-tests
so we don't have to use a wrapper around WebElements.

BUG=None
TEST=The new code is not yet enabled. Test that the password autocomplete still
     works as expected.
