[kernel] Add two new kernel tools; add error handling in existing tools. This CL adds two new kernel tools which can answer questions about a dill file: * count_breakdown.dart Enumerates the different node types in the provided dill file and counts them. This has proved useful in the past to e.g. see how many doubles are included in Flutter. * size_breakdown.dart Gives an overview of which parts of the dill file contributes how many bytes. This has proved useful in the past to see that the string table gets huge when we have many doubles (because we currently save doubles in kernel as strings). It also adds error handling and usage information to existing tools.
