Lioncash d6a60050ff VideoVulkan/ShaderCompiler: Use a std::optional instead of bool+out variable
Now that we utilize C++17, we can simply return an optional containing
the code instead of using an out variable and a boolean result,
essentially combining them into one.

This provides a much more straightforward interface.
