Alexandros Mandravillis 57f0505bd2 Widen lui and bltz screen_x_sites: a screen X kept in the high half

A renderer that keeps a screen X as SX << 16 tests the right edge against
a lui-held W << 16 and the left edge with bltz on the shifted value. No
explicit [widescreen.cull] kind fits either: bltz_sites compares the whole
register with -margin, and a lui at a screen_x site was a build error.

screen_x_sites now also takes
  lui rt, W        -> rt = (W + margin) << 16
  bltz x, outside  -> taken while SX < -margin   (x = SX << 16)
Both are the identity at 4:3. The helpers are defined for native code and
for overlay shards; their math is in ws_cull_edge.h. The two prototypes are
written only for a config that lists screen_x_sites, so the generated code
of every other title is unchanged.
