This commit just adds a miptail start field to isl_surf and wires it up
in the RENDER_SURFACE_STATE and 3DSTATE_DEPTH code. We also add a
minimum miptail LOD so that client drivers have a knob to control the
miptails a bit.

With these tilings, everything is aligned to a tile and the tiled
surface size calculations will handle the array stride for us. We need
to provide an accurate 4D size so that 3D and multisampled images get

Depth/stencil surfaces cannot be linear but they can be 1D, so they
end up being tile64 when sparse (as we force every sparse resource to
be either tile64 or linear).
According to the "1D surfaces" page from BSpec, our driver treats 1D
surfaces as 2D surfaces with a height of 1 texel, since we don't
enable the corresponding bit from HAS_SLICE_CHICKEN7. And since we
support 2D surfaces, we should also support 1D.
