anv/pipeline: Add sample locations for gen7-7.5
V1: Add multisample positions (Nanley) V2: Fix 8x sample positions to match OpenGL (Anuj) V3: Vulkan has standard sample locations. They need not be same as in OpenGL. (Anuj) Signed-off-by: Anuj Phogat <[email protected]> Reviewed-by: Jason Ekstrand <[email protected]>
