renderer_vulkan/shader: Add helper GLSL shaders

These shaders are used to specify code that is not dynamically generated
in the Vulkan backend. Instead of packing it inside the build system,
it's manually built and copied to the C++ file to avoid adding
unnecessary build time dependencies.

quad_array should be dropped in the future since it can be emulated with
a memory pool generated from the CPU.
