qcacld-3.0: Add initial roam offload state changes

Rename the existing roam offload states to include
WLAN_ prefix. Add 2 new states:
WLAN_ROAMING_IN_PROG - Roaming has started at firmware, this is
                       after candidate selection at firmware.

WLAN_ROAM_SYNCH_IN_PROG - State after handoff is complete at
                          firmware.

Also move the roam_offload_state enum to connection manager.
