[milestone][SPIRV] GPU particle system Vulkan sample

[s-perron]

Make the GPU particle system sample in the Sascha Wilems Vulkan samples work.

The main featured used that still need to be implemented are:

• [HLSL][SPIR-V] Add RWStructutredBuffer type support for SPIR-V llvm-project#124558
• [HLSL][SPIRV] Add constant buffers for SPIR-V llvm-project#124597
• [HLSL][SPIRV] Implement system value semantic SV_DispatchThreadID llvm-project#136984
• [HLSL][SPIRV] Implement vk::builtin llvm-project#136898
• [HLSL][SPIRV] Implement vk::location llvm-project#136893
• [HLSL][SPIRV] Implement user defined semantics llvm-project#136993
• [HLSL][SPIR-V] Push constants in HLSL llvm-project#124581
• [HLSL][SPIRV] Implement vertex shaders llvm-project#136961
• [HLSL][SPIRV] Implement fragment shaders llvm-project#136962
• [HLSL][SPIRV] Implement system value semantic SV_POSITION llvm-project#136969
• [HLSL][SPIR] Add Texture* and RWTexture* types to the SPIR-V backend llvm-project#124566

Items are checked off when the issue is far enough along to make this sample work.
