RNA/UI: Allow displaying in tooltip why RNA property isn't editable

This commit allows RNA properties to return additional info on their editable state which may then be displayed in tooltips. To show how it works, it also adds some info for the editable check of proxies. For generally un-editable properties or properties of a linked data-block, RNA returns default strings.
