* COM-ify all slang-gfx interfaces.

* Make `gfx::Renderer` a COM interface.
This is a first step towards making the `gfx` library expose a COM compatible DLL interface. Remaining classes will come as separate PRs.
* Fixup project files
* Fix calling conventions
* Make gfx::create*Renderer() functions increase ref count by 1
* Make renderer createFunc return via out parameter

* GPU Foreach Loop
This PR introduces the completed GPU foreach loop and updates the
heterogeneous-hello-world example to use it. This PR builds on the
previous introduction of the GPU Foreach loop parsing and semantic
checking PR (#1482) by introducing IR lowering and emmitting. THe new
feature can be used by having a GPU_Foreach loop interacting with a
named non-CPP entry point, and using the -heterogeneous flag.
* Fix to path

This PR introduces parsing and semantic checking for a GPU foreach loop
for heterogeneouis programming. A GPU foreach loop takes the form:
```
__GPU_FOREACH(renderer, gridDims, LAMBDA(uint3 dispatchThreadID) {
kernelCall(args, ...); });
```
And will allow the host code to call into a kernel with the correct
renderer and grid dimensions. This commit also introduces a hack to
unify types in the heterogeneous hello world file, which will hopefully
be amended in the future.

* Binary Heterogeneous Example
This PR introduces the ability to insert the binary of a non-CPU target
by using the -heterogeneous flag. Specifically, this PR updates the
emitting logic to produce a variable of name `__[name_of_entryPoint]`
when the heterogeneous flag is present.
* Prelude path fix

* Baseline Heterogeneous Example
This PR introduces a baseline heterogeneous example, including both a
Slang file and an associated C++ helper file. This refactoring
primarily moves the Slang file "into the driver's seat" while
maintaining that the C++ side still does most of the actual work.
* Fix to prelude path

* CPU/GPU Compute Shader Example
This PR introduces an example to run a simple compute shader on the GPU
in the heterogeneous-hello-world example. All loading code is currently run in
C++, so the heterogeneity of this example is still a work in progress.
This change updates exactly this example, and so should not cause
issues elsewhere in the codebase.
* Small fix
* Added gfx to help the linker
* Added back the struct
* Updated premake to respect windows conditions
* Completely removed het-example
* Re-added example

* Introduced heterogeneous example. Example includes C++ source and
header files, and does not currently make use of the associated slang
file when building. The intent of this commit is to introduce the
example as a baseline for later updates as the heterogeneous model is
expanded.
* Changing namespace
* Renamed and rewrote README
* Updated example to account for compiler updates
* Updated path
