qcacmn: Add interface APIs b/w mlme and serialization

Add the interface layers APIs that will be utilized by the mlme
module to interface with the serialization module.
Also add a serialization command cancel option to cancel cmds of a vdev
belonging to a given command type and define the vdev mlme legacy callback
function that will be used by the mlme-serialization interface APIs
