anv,iris: Use the data cache for UBO pulls on Gen12+

Browse source 
Now that we have the HDC, using the data cache for UBO pulls seems to
help things quite a bit:

    GTA V DXVK              104.0%
    Talos Principle GL      102.8%
    Rise of Tomb Raider VK  102.8%
    Dark Souls 3 DXVK       101.4%
    Witcher3 DXVK           101.3%
    Bioshock Infinite GL    100.5%
    Doom 2016 VK            97.7%

Doom is a bit of a loss but it helps enough other stuff, it's probably
worth the hit.
