NVStore: add the allocate_key API (instead of set_alloc_key)

Add the allocate_key API. This replaces the previously added set_alloc_key API
(which allocates a key and sets the value at the same time).
Reason for the change: Key allocation will typically be used by other storage
features (like StorageLite), keeping the allocated keys in another location.
Previous API created problems in the case key allocation and value setting
couldn't be done at the same time (for instance, if the set value was
derived from the allocated key, such as hash or CMAC).
