Anisotropic Filtering now works with OpenGL on Linux RDNA 3 GPU (never worked before), no issues with Vulkan. |

Description of Changes
Rationale behind Changes
AMD requires miplevel of 2 for anisotropic filtering to work so let's do so, also make the changes across the board for consistency.
Seems that aniso lower levels is more aggressive on amd as well, modifying LoDBias doesn't have any effect in Device but it does in shader, but that's another issue.
Also aniso is a bit more aggressive on amd than on nv/intel in any level.
Suggested Testing Steps
Make sure aniso still works on all renderers and all gpu vendors, check if aniso is fixed on dx11/12 on amd.
Did you use AI to help find, test, or implement this issue or feature?
