…ate steps in gen_vulkan_spv ## Changes * As title * Also removed caching mechanism for the codegen step for simplicity, and ad hoc latency testing didn't reveal any improvements from caching this step ## Motivation As written, gen_vulkan_spv has a potential bug where generated header files are out of date when SPIR-V compilation occurs. Due to the parallelization of SPIR-V compilation, it's possible for a generated GLSL file to be processed before header files that it uses are generated. The fix is to separate the steps of code generation and SPIR-V compilation, such that code generation finished before SPIR-V compilation occurs.
