GPU: Add placeholder for Vulkan backend. This patch adds a placeholder for the vulkan backend. When activated (`WITH_VULKAN_BACKEND=On` and `--gpu-backend vulkan`) it might open a blender screen, but nothing should be visible as none of the functions are implemented or otherwise crash on a nullptr. This is expected as this is just a placeholder. The goal is to add shader compilation +validation to this backend as one of the next steps so we can validate changes to existing shaders on OpenGL, Metal and Vulkan at the same time.

GPU: Compile vulkan shaders to Spir-V binaries. Compile each static shader using shaderc to Spir-V binaries. The main goal is to make sure that the GLSL created using ShaderCreateInfo and able to compile to Spir-V. For the second stage a correct pipeline needs to be created and some shader would need more adjustments (push constants size). With this patch future changes to GLSL sources can already be checked against vulkan, without the backend finished. Mechanism has been tested using MacOS and MoltenVK. For other OS, we should finetune CMake files to find the right location to shaderc. ``` ************************************************************ *** Build Mon 12 Dec 2022 11:08:07 CET ************************************************************ Shader Test compilation result: 463 / 463 passed (skipped 118 for compatibility reasons) OpenGL backend shader compilation succeeded.

GHOST: Vulkan Backend. This adds a vulkan backend to GHOST. The code was extracted from the tmp-vulkan branch. The main difference with the original code is that GHOST isn't responsible for fallback. For Metal backend there is already an idea that the GPU module is responsible for the fallback, not the system. For Blender we target Vulkan 1.2 at the time of this patch. MoltenVK (needed to convert Vulkan calls to Metal) has been added as a separate package. This patch isn't useful for end-users, currently when starting blender with `--gpu-backend vulkan` it would crash as the `VBBackend` doesn't initialize the expected global structs in the GPU module. Validated to be working on Windows and Apple. Linux still needs to be tested. Reviewed By: fclem Differential Revision: https://developer.blender.org/D13155
