Desktop GLSL input + Vulkan GLSL output in shader_translator

This is a sample program that can be used to compile a shader and inspect the intermediate tree or the output from the shader translator. This change adds support for the recently added desktop GLSL inputs as well as the ability to produce Vulkan GLSL output.
