Subject: Remove old code paths from render-test (#1760)

* Remove old code paths from render-test

Historically, the `render-test` tool was using three different code paths:

* One based on `gfx` and manual (non-reflection-based) parameter setting, used for OpenGL, D3D11, D3D12, and Vulkan
* One for CPU that used reflection-based parameter setting but shared no code with the first
* One for CUDA that used reflection-based parameter setting and shared some, but not all, code with the CPU path

Recently we've updated `render-test` to include a fourth option:

* Using `gfx` and the "shader object" system it exposes for a unified reflection-based parameter-setting system taht works across OpenGL, D3D11, D3D12, Vulkan, CUDA, and CPU

This change removes the first three options and leaves only the single unified path. A sa result, a bunch of code in `render-test` is no longer needed, and the codebase no longer relies on things like the `IDescriptorSet`-related APIs in `gfx`.

Several existing tests had to be disabled to make this change possible. Those tests will need to be audited and either re-enabled once we fix issues in the shader object system, or permanently removed if they don't test stuff we intend to support in the long run (e.g., global-scope type parameters, which aren't a clear necessity).

* fixup: CUDA detection logic
