freedreno/a4xx: only align slices in non-layer_first textures

Browse source 
When layer is the container, slices are tightly packed inside of each
layer. We don't need any additional alignment. On a3xx, each slice
contains all the layers, so having alignment makes sense.

This fixes a whole slew of array-related piglits, including texelFetch
and tex-miplevel-selection varieties.
