qcacmn: Introduce new versions of TDLS peer callbacks

The parameters to function typedef tdls_register_tl_peer_callback()
currently includes ucastsig.  This "unicast signature" parameter dates
back to a previous version of the driver that used signatures to
synchronize the data plane with the control plane. However the current
version of the driver does not use this mechanism, so there is a
desire to remove this parameter from the callback.

In addition both typedef tdls_register_tl_peer_callback() and typedef
tdls_deregister_tl_peer_callback() suffer from poor naming since the
"_tl_" in the names refers to a datapath component that was present in
an older version of the driver but which is no longer present.

Therefore introduce a new version of these typedefs with better naming
and which removes the ucastsig parameter.

Use temporary conditional compilation to allow support for both the
old and new interfaces until such time as all registrants have
converted to the new interfaces. This is part of the plan to
completely remove the obsolete unicast and broadcast signatures from
throughout the driver.
