intel: Implement Gen12 workaround for array textures of size 1

Gen12 does not support RENDER_SURFACE_STATE::SurfaceArray = true &&
RENDER_SURFACE_STATE::Depth = 0. SurfaceArray can only be set to true
if Depth >= 1.

We workaround this limitation by adding the max(value, 1) snippet in
the shaders on the 3 components for texture array sizes.

Tested on Gen9 with the following Vulkan CTS tests :

v2: Drop debug print (Tapani)
    Switch to GEN:BUG instead of Wa_

v3: Fix dEQP-VK.image.image_size.1d_array.* cases (Lionel)

v4: Fix dEQP-VK.glsl.texture_functions.query.texturesize.* cases
    (Missing tex_op handling) (Lionel)

v5: Missing break statement (Lionel)

v6: Fixup comment (Tapani)

v7: Fixup comment again (Tapani)

v8: Don't use sample_dim as index (Jason)
    Rename pass
    Simplify control flow
