radv: Enable NGG culling by default on GFX10.

Browse source 
We never took the time to actually test this, but it works fine.
Improves performance on Navi 10 in the following test cases:

Baldur's Gate 3 Vulkan: up to 10%
Witcher 3 D3D11: around 4%
Granite primitive stress test: 107%
FSR2 sample app: 57%

Notes:
NGG is still disabled on Navi 14.
Not tested on Navi 12.
