Move anisotropic filtering support check to a function

Support check for anisotropic filtering was done inside of iterate.
This change moves that check inside of a function for consistency
and performance.

Affects:

dEQP-VK.texture.filtering_anisotropy.*

Components: Vulkan

VK-GL-CTS issue: 3068
