[PATCH 3/4] ui/vnc-clipboard: factor out clipboard peer registration

VNC clipboard peer is registered inline from vnc_server_cut_text_caps.

Move the registration logic into a function so a subsequent change can
register the peer independently of extended clipboard capability.

No functional change.
