Bugfix #19729: Color Ramps are not animatable (Part 1)

This first part of the fix makes it possible to animate ramp settings by making sure that the paths for ramps and their elements can be determined. While the code for constructing the path to the ramps is relatively simple, the code for the elements is a bit more involved :/

However, this commit only fixes the paths, but most of the ramp settings still cannot be keyframed directly from the UI buttons/widgets (i.e. from Material/Texture buttons) since the buttons still use the old layouts.
