Change #6250 introduced shader handling a map of includes and defines. The defines map was directly passed to the preprocessor, which used it internally when handling
#ifdef
type of code.As our preprocessor does not handle generic defines, for example
#define LOD_LEVEL 4
which can then be used anywhere in the following code, the implementation has changed to allow this.This PR converts all defines specified in the define map to source code, and this is attached to the shader source code directly. This allows us to pass on processing of those defines to the actual platforms that compiles the shader.
