thejayman77 3d27095c2b QSF: revert to AGGRESSIVE AREA + surgical MAX_FANOUT on Z-req raddr (close EMIF, keep design clk) ...

Fit data: AGGRESSIVE AREA gives design clk +0.631 / EMIF -0.103; global BALANCED
flipped it to EMIF +0.084 / design clk -6.119 (vert_count->texcache swung 6.7ns).
AGGRESSIVE AREA is far closer to closing, so keep it and fix the one 310MHz EMIF
miss surgically: MAX_FANOUT 3 on u_zc_emit|u_req|raddr_hi1_q forces the register
duplication Quartus asked for (TMC-20551) without the global placement disruption.
