Also fragmentize bluetooth tethering screen.

* Add WifiSettingsForSetupWizardXL as a new Activity
The activity has WifiSettings fragment in it. It also contains
several buttons, texts around the fragment.

* Making configuration UI part of Preference list.
In Wifi Setup for Setup Wizard XL, WifiSettings fragment lets
a UI for configuring access points shown inside a
PregerenceCategory object, while it has been shown as Dialog.

To achieve this action, WifiDialog is decomposed into two parts:
- WifiConfigUiBase (Mainly UI part)
- WifiConfigController (Mainly Wifi controller part)

All codes for wifi configuration in WifiDialog is now in
WifiConfigController, which is reused from
WifiConfigPreference.

* Misc stuff
- Remove AccessPoint#compareTo(). Instead,
  AccessPoint.AccessPointComparater should be used when needed.

The logic calling selectFirst() is removed as
- There's no comment why it is needed.
- Actually SetupWizard gets stack as that forces users to see
  WirelessSettings in SetupWizard.

The other changes:
- Move back LocalePickerFragment to LocalePicker.
- Make <activity> for LocalePicker in AndroidManifest <activity-alias>
- Add a short comment about how getComponent(), which should be a key
  for understanding how top-level settings work.
- Modify LanguageSettings so that it corectly points LocalePicker as
  a fragment.

- Add button bar feature toward SettingsPreferenceFragment,
  which has existed in PreferenceActivity and has been used
  (probably) only by Settings app.
- super.onActivityCreated() is not called at the beggining of
  WifiSettings#onActivityCreated(), the parent method assumes
  the child should have prepared PreferenceScreen, while
  WifiSettings cannot do until the parent Activity is ready.
- Call SetHasOptionMenu() should be called AFTER the parent
  Activity is ready. It is not documented, so it would be better
  to file another bug.
- Add exception to proguard...

Bug: 2933151

Need to add proguard.flag, as the Activity crashes without it.
