recovery: Configure device menu based on runtime info.

Drop the dependency on build time flag of AB_OTA_UPDATER when compiling
device.cpp. Note that AB_OTA_UPDATER still guards the package install
behavior (install.cpp).

This can be extended to cover the entry of "Apply update from SD card".

Test: Build and boot into recovery on angler and walleye respectively.
      Check the recovery menu.
