Vulkan: Uber-shader support
For each internal shader, there is now possibly a companion .json file
that defines shader variations. The variations consist of a set of
flags and a set of enums. Each enum defines a variation that takes one
of a few values. Flags are shorthands for 2-value enums.
In the shader code, #if can be used to change the shader based on
variations derived from flags and enums. On the C++ side, those
variations are combined into an index and the appropriate shader is
retrieved from a table.
