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.
