radv: add a layer for fixing rendering issues with RAGE2

This game seems to incorrectly set the render area and since we switched
to full dynamic rendering, the framebuffer dimensions is no longer used.

Forcing the render area to be the framebuffer dimensions restore the
previous logic and it fixes rendering issues.

Fixes: c7d0d328d56 ("radv: Set the window scissor to the render area, not 
framebuffer")
