MSL: Fix '--msl-multi-patch-workgroup' out of bounds reads when dispatching more threads than control points (#1662)
* Fix '--msl-multi-patch-workgroup' cases where thread count exceeds data bounds

*Fix gl_PrimitiveID off by one error when computing last valid index
*Point gl_out to the last patch's data when threads exceed input data bounds
*Point patchOut to the last patch's data when threads exceed input data bounds

* Update MSL test expectations.

* Undo change to MSL multi-patch hull output bound checks

* Update MSL multi-patch test expectations.

ae9ca7d73c MSL: Fix copy of arrays to/from stage IO variables.
Need to take into account effective storage classes and whether or not
we target stage IO blocks since native arrays are conditionally enabled.

682a227f4b MSL: Make builtin argument type declaration context sensitive.
Sometimes we'll need array template, sometimes not 🤷.

c1edd35d57 MSL: Use spvUnsafeArray for builtin arrays after all.
It will get too messy to deal with constant initializers any other way,
so just deal with complexity in argument_decl instead ...

23da445bd4 MSL: Emit multiple threadgroup slices for multi-patch.
Multiple patches can run in the same workgroup when using multi-patch
mode, so we need to allocate enough storage to avoid false sharing.

46c48ee6b5 MSL: Rewrite how IO blocks are emitted in multi-patch mode.
Firstly, never flatten inputs or outputs in multi-patch mode.
The main scenario where we do need to care is Block IO.
In this case, we should only flatten the top-level member, and after
that we use access chains as normal.

Using structs in Input storage class is now possible as well. We don't
need to consider per-location fixups at all here. In Vulkan, IO structs
must match exactly. Only plain vectors can have smaller vector sizes as
a special case.
