gallium: separate depth0 and array_size in the resource itself.
These fields are still mutually exclusive (since no 3d array textures exist)
but it ultimately seemed to error-prone to adapt all code accept the new
meaning of depth0 (drivers stick that into hardware regs, calculate mipmap
sizes etc.). And it isn't really cleaner anyway.
So, array textures will have depth0 of 1, but instead use array_size,
3D textures will continue to use depth0 (and have array_size of 1). Cube
maps also will use array_size to indicate their 6 faces, but since all drivers
should just be fine by inferring this themselves from the fact it's a cube map
as they always used to nothing should break.
