Revert "Partially revert "modify quick settings to adopt the accessibility state api""

This reverts commit 7a64815b.

And added the info.setText() part in onInitializeAccessibilityNodeInfo()
in QSTileBaseView.java so that related tests are not broken.

Test: tested with quicksettings and
android.platform.test.scenario.sysui.quicksettings.ToggleWifiOn#testToggle (pass)
and android.platform.test.scenario.sysui.statusbar.NotificationIconOverflow#testNotificationOverFlow
(fails without and with my cl).
