[SB][Wifi] Display hotspot device type in QS tile.

Bug: 265342892
Test: `adb shell am broadcast -a com.android.systemui.demo -e command
network -e wifi show -e hotspot {tablet/laptop/watch/etc}` -> verify QS
tile displays an icon matching the hotspot device type. Verify status
bar does *not* display the hotspot device type.
Test: atest InternetTileViewModelTest WifiViewModelTest
