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. Shader Test compilation result: 529 / 529 passed (skipped 52 for compatibility reasons) Vulkan backend shader compilation succeeded. ``` Reviewed By: fclem Maniphest Tasks: T102760 Differential Revision: https://developer.blender.org/D16610
