md-join-pane, cmd-split-window, cmd-resize-pane: use shared floating-pane

Browse Source 
redraw instead of full client redraw

The three interactive mouse-drag paths that move or resize a floating
pane (move-pane -M's Alt-drag, split-window/new-pane's interactive
resize, and resize-pane's own border drag) each unconditionally called
server_redraw_window(w), redrawing every pane in the window for a change
that only ever disturbs the floating pane's own old and new rectangle.
Switch all three to window_pane_redraw_floating().
