lib: sm: Enable VM tracking for the SPD

Provide the VM tracking API on the SPD to
fix build failures. We do not get availability
messages in this configuration, but we might still
be able to do some basic VM lifetime tracking
for the compatibility VM 0 by tracking transitions
from the bootloader to the non-secure OS.
