  Message : Vulkan: Implement basic uniform shader parsing. This is a first step at implementing uniforms with descriptor sets. It does not actually bind uniforms and upload data, but it does implement uniform shader parsing. Uniforms are gathered into a single uniform block which is bound to set 0, with binding 0 for vertex uniforms and binding 1 for fragment uniforms. Also adds a ReplaceSubstring helper to string_utils. Also removes the precision writing from OutputVulkanGLSL since this was generating warnings with glslang.
