video_core: keep root tables and bind table 0 as constant bank 17

The 3D methods 0x504/0x508 write eight 256-byte root tables, which
shaders read as constant banks 24-31; NVN2 keeps push constants in table
0 (bank 17 after the Ampere lowering). Fire Emblem: Fortune's Weave
keeps its material constants there and never binds bank 17, and the
blit constants pass replaced those reads with render-target sizes,
flooding its 3D scenes red.

Maxwell3D now keeps the tables, the buffer cache streams table 0 as bank
17 when the game has not bound one, and the blit constants pass leaves
shaders that read bank 17 outside its parameter block alone.
