[Autofill] Phone number cleanup.

Lots of little things:
 * In PhoneNumber, use the cached_parsed_phone_ for requests for the whole number as well as for other requests.
 * Updated the comment within PhoneNumber::SetInfo() to reflect what the method actually does.
 * Add a test to verify that cached phone numbers are correctly invalidated and updated.
 * Remove ParsePhoneNumberInternal() in favor of using ParsePhoneNumber() throughout.
 * Remove a redundant parameter to ConstructPhoneNumber()
 * Use hacker_case for simple accessors in PhoneObject
 * Factor out shared code in phone_number_i18n.cc
 * Make sure to clear the incoming PhoneNumber argument to ParsePhoneNumber(), as libphonenumber doesn't do this for us.
 * Dramatically simplify the implementations for NormalizePhoneNumber(), ConstructPhoneNumber(), and PhoneObject::GetWholeNumber() by relying on factored out shared code.
 * Fix PhoneObject::operator=() to copy the whole_number_ as well as the other fields.  (FWIW, since whole_number_ is usually computed from i18n_number_, this only rarely caused problems.)
 * Remove the explicit UI thread and MessageLoop from PhoneNumberI18NTest now that they're no longer needed.
