Hypershade-style pin display modes for material graph nodes

Browse Source 
Each node gets an All/Conn toggle: connected-only mode hides
unconnected pins behind collapsed connector nubs on the title row;
dragging a link onto (or from) a nub opens a menu to pick which hidden
pin to wire, and the pin appears once connected. The toggle is drawn
and hit-tested geometrically, and its tooltip is deferred to after
NE::End() so it lands at the cursor. A new Preferences > Material
checkbox opts into persisting the per-node mode as USD customData
(uiShowAllPins); otherwise it stays session-only.
