Subject: MVP for higher order functions (#2849)

* MVP for higher order functions

* Add shader subgroup partitioned glsl intrinsics

* Implement parsing and checking for tuple types

Currently there is no way to do anything useful with them from the source language however

* neaten

* Correct precedence of function type parsing

* neaten

* higher order function tests

* function types of any arity

* Inference for higher order functions

* Add second test for unsynchronized params

* regenerate vs projects

* dx11 -> dx12 for saturated cooperations tests

* Disable saturated cooperation tests on vulkan

They fail on release builds in CI, not essential for the higher order function work however

* remove saturated-cooperation tests

* Remove unnecessary assert and clarify control flow in AddDeclRefOverloadCandidates

* Add Tuple type name mangling

* Use functype keyword to introduce function types

* Add more inference tests for hof
