anv/image: Fix initialization of the ISL tiling

If an internal user creates an image with Vulkan tiling VK_IMAGE_TILING_OPTIMAL
and an ISL tiling that isn't set, ISL will fail to create the image as
anv_image_create_info::isl_tiling_flags will be an invalid value.

Correct this by making anv_image_create_info::isl_tiling_flags an opt-in,
filtering bitmask, that allows the caller to specify which ISL tilings are
acceptable, but not contradictory to the Vulkan tiling.

Opt-out of filtering for vkCreateImage.
