This adds interface panels to organize the Cache File UI parameters for modifiers and constraints into related components: velocity, time, and render procedural. Properties relating to the three aforementioned components are separated from `uiTemplateCacheFile` into their own functions (e.g. `uiTemplateCacheFileVelocity` for the velocity one), which are in turn called from the specific panel creation routines of the modifiers and constraints (for constraints, the functions are exposed to the RNA). `uiTemplateCacheFile` now only shows the properties for the file path, and in the case of constraints, the scale property. The properties that are only defined per modifier (like the velocity scale), are shown in the proper modifier layout panel if applicable.
