Bluetooth: kconfig: Put 'menuconfig BT' in top-level menu

The 'Bluetooth' menu contains just 'config BT' and its indented
children.

Remove one menu level by removing the 'Bluetooth' menu and turning BT
into a 'menuconfig' symbol. Also change the prompt from "Bluetooth
support" to just "Bluetooth", to make it consistent with e.g. "Logging".
