Revert "Revert "SettingsProvider enhanced cache""
This reverts commit b8d8b9332e94351e6d9e0b8ec713a17ba55ab8be.
Reason for revert: Reland with change
The change is to make all pre-defined settings cache-able regardless if
they exist or not. For example, if Launcher repeatedly queries a
predefined but unset setting like show_hidden_icon_apps_enabled, it
doesn't need to repeatedly do binder calls.
This also fixes the test failure that caused the first revert.
