MSL: Rewrite tessellation_access_chain.

To support loading array of array properly in tessellation, we need a
rewrite of how tessellation access chains are handled.

The major change is to remove the implicit unflatten step inside
access_chain which does not take into account the case where you load
directly from a control point array variable.

We defer unflatten step until OpLoad time instead.
This fixes cases where we load array of {array,matrix,struct}.

Removes the hacky path for MSL access chain index workaround.
