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.

Clean up AddDefaultReturnStatements
It doesn't need to use a traverser, since all function definitions can
be found simply by iterating over the children of the root node.

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.
