Slang -> CUDA kernel runs correctly in test infrastructure (#1167)

* First pass at BindLocation.

* Added BindSet::init - for initializing with two input constant buffers. Needs better name, and perhaps should be another class.

* Fix handling of constant buffer stripping.
Improved initialization.

* Trying to generalize BindLocation a little more.
Split out CPULikeBindRoot.

* More work to make BindLocation et al work with non uniform bindings.

* Added parsing to a location.

* WIP: Trying to get CPU working with BindLocation.

* Describe problem of knowing the type of the reference point in the binding table.

* More ideas on getBindings fix.

* Remove BindSet as member of BindLocation.

* Added BindLocation::Invalid

* Made BindLocation able to be key in hash

* Use BindLocation for bindings on BindingSet.

* Added cuda and nvrtc categories to test infrastructure.
Disabled CUDA synthetic tests by default.
Fixed such that all tests now produce something in BindLocation style.

* Use m_userIndex instead of m_userData on Resource.
Move the binding setup out of cpu-compute-util (as no longer CPU specific)

* Removed CPUBinding - used BindLocation/BindSet instead.
Fixed some bugs around indexOf around uniform indirection.

* Renamed BindSet::Resource -> BindSet::Value.

* Document BindLocation.

* Fixes for Clang/GCC
Improve invariant requirement handling when constructing from BindPoints.

* WIP: First attempt to run CUDA kernel.

* Fix some issues around doing CUDA kernel launch.

* Fix issues around use of cudaMemCpy .

* Better cuda runtime error checking mechanism.

* Fixed bug in passing parameters to cuda kernel launch.
Simplified initialisation of context.

* WIP: Fix CUDA runtime issues.

* Add explicit CUDA synchronize so failures don't appear on implicit ones.

* Fix problem emitting non shared variable on CUDA.

* Fix some typos in CUDA layout.
Use just a pointer for now for CUDA StucturedBuffer.

* Arg order for CUDA launch was wrong.

* First compute kernel runs on CUDA.
