Vulkan: Implement new GLSL translator back-end.
The Vulkan GLSL translator back-end will handle validating and
translating our WebGL/ESSL shaders into Vulkan-specific GLSL.
glslang (the Vulkan one) accepts both GLSL and GLSL ES shaders
as inputs, and both the desktop and ESSL back-ends give
incompleteness warnings when used. For now, use the desktop GL
450 as a target for Vulkan GLSL.
The Vulkan-specific changes are currently only to add locations
to every vertex input and fragment output.
