For 2D array views of 3D images, the layer of the view corresponds to
the depth (instead of the layer, which should be always 0) of the image.
Fix the code emitting deferred RTA clears to set the depth instead of
the layer of the image to clear.
Fixes the flakiness of `dEQP-VK.renderpasses.renderpass*.
remaining_array_layers.multi_layer_fb.*`.
Fixes: 95820584d0 ("pvr: Add deferred RTA clears for cores without gs_rta_support.")
