Copied main logic from WifiSettings into WifiSettings2, removing
all instances of WifiTracker in preparation of adding WifiTracker2.
Removed:
- WifiDialog (to be added back in)
- Context Menu (to be added back in)
- Leftover SUW code (Next button)
WifiSettings2Test also copied directly from WifiSettingsTest, without
context menu test.

Use WifiSettings2 if settings_wifitracker2 feature flag is enabled.
WifiSettings2 will be used for changes to WifiSettings to incorporate
the WifiTracker2 refactor.
Bug: 70983952
Test: make, set feature flag, open Wifi settings to verify new page
opens.

Use arrays.xml to store translations for enumerations;
avoid race conditions happened when pop up menu or dialog;
avoid saving configurations with networks disabled;
use the same layout for all the dialogs;
support editing EAP networks;
only unlock keystore before connecting;
and many bug fixes I cannot remember.
The number of lines in the new code is about 1/3 of the old one,
and it improves the readability a lot!
