freedreno/turnip: RESINFO for shader image sizes
freedreno: Use RESINFO for image size queries.
The closed GL driver uses resinfo on images with the writeonly flag (using
the texture-path's getsize only for readonly images). The closed vulkan
driver seems to use resinfo regardless.
Fixes dEQP-VK.image.image_size.* other than texel buffer (since we haven't
implemented their descriptors yet).
