Create the Wifi Network Details Page.
This page should not be searchable, as it corresponds to a specific access point, thus click on a search result would not have an access point in which to open. Fix WifiPicker bugs b/35883232 and b/35951638 that deal with UI jank. Bug: 34713316 Test: Tracked in b/35963536 and to be implemented in an immediate follow up CL. Change-Id: Iad7f26c7f04c3fc7d07a8e9188843eeb4d44cd36
