qcacld-3.0: wma to target_if migration of wmi_roam_event

Currently, wmi_roam_event_id data is extracted and processing is
also done in wma. This is not inline with component model where
target_if takes care of data extraction and handover the extracted
data to corresponding component(connection mgr in this case).
Add changes to support the same. As the legacy CSR/LIM is not
yet converged, have a wrapper from connection mgr to wma to call
these legacy APIs.
