Add BackendType for standalone backends

Browse Source 
All backends should have a BackendType to enable statistics reporting
per BackendType.

Add a new BackendType for standalone backends, B_STANDALONE_BACKEND (and
alphabetize the BackendTypes). Both the bootstrap backend and single
user mode backends will have BackendType B_STANDALONE_BACKEND.
