gfx-shader-param-basic: Support for scaling and fix enumerations 

Scaling is now fully supported for Floats and Integers, which allows much higher precision inputs, or upscaling to a different range. Complex functions for scaling are not supported as those would be a scripting thing and should be kept as that (OBS Studio has built in Lua scripting).

Additionally, enumerations are now correctly loaded with data.
