radv: configure the screen scissor to the maximum image dimension

Browse source 
The framebuffer dimension exposed to apps is still 16k but since the
driver allows 32k image on GFX12+, meta operations might perform
operations (like a copy) using graphics.

While we are at it, use the correct bitfield for setting BR_X/BR_Y on
GFX12.
