Title: DOC: Clarification notes for (apparently) merge-related tools

This adds a note to the docstring for each of `iris.cube.Cube.is_compatible()` and `iris.util.describe_diff()` to clarify that neither of these functions are designed as merge reporting tools and that a return value of `True` does not guarantee the two cubes will merge.
