* Shader -> SPIR-V at CTS build time (#1849) Instead of relying on prebuilt checked-in SPIR-V files, compile available shaders at CTS build time. * Add dependency on glslc (available as part of VULKAN_SDK). * Add optional build flag BUILD_GLSL_SHADERS, OFF by default. * Remove pre-built SPIR-V files * Compile Shader -> SPIR-V at CTS build time * Use glslangValidator for shader -> spirv * Add glslangValidator tool for shader -> spirv * Refactor glslangValidator tool retrieval * Address review comments * Use add_subdirectory() instead of include() * Use glslang instead of glslangValidator * Update Github actions CI to install Vulkan SDK
