iris: make sure DS and TE are sent in pairs on >= gfx125

Browse source 
We have couple of dynamic fields used on >= gfx125, ScratchSpaceBuffer
and TessellationDistributionMode. There are also 2 workarounds dealing
with TessellationDistributionMode. These changes make sure that we
always emit both DS and TE together when the dynamic fields need to be
changed.

This fixes KHR-Single-GL46.arrays_of_arrays_gl.AtomicUsage on MTL.
