debug: remove param hooks, isolate arrow loop hang

Removed PCLandscape, SpriteRegion, and HUD param hooks (served their
purpose, may interfere). Arrow loop hangs — gets past 'starting arrow
loop' but never reaches 'arrow loop done'. The GfxDir__FindEntry or
display vtable call inside the arrow loop is blocking/looping.

Likely cause: GfxHandler state corrupted by a prior section, or
display layer context invalid for the arrow loop iterations.
