Adds support for enumerations, a different way of selecting how something should behave in a shader. Enumerations rely on a continuous list of values, and will automatically detect how many values there are in the enumeration. Only non-vector types are supported as enumeration entries, and array/vector parameters can have each member set to a different enumeration value. Furthermore suffixes now are properly assigned, and 'bool' no longer causes shaders to stop rendering. Additionally by inlining some functions and using std::string_view we can achieve a slightly better performance than before.
