Show L2-connected Network Request

NetworkRequestEntries are only created at L3 connection, but this means
we don't show network requests in the middle of connection in the
network specifier dialog. Make sure we create NetworkRequestEntries
based on L2 connected data (via WIFI_NETWORK_STATE_CHANGED) so the
network specifier dialog shows the connection progress.

Bug: 292064115
Test: atest WifiPickerTrackerTest, manually verify network specifier
dialog shows connection progress.
