This saves about 270KB of codesize on Linux64 without LTO, or 20KB with LTO. The basic idea is that we can flag dictionaries that need to-JS conversion (hence ToObjectInternal) based on various IDL uses (return value in normal interface, argument in callback, etc) and then annotate the ones that are converted to JS manually in C++ code. The mozwebidlcodegen changes are needed because non-local changes (e.g. whether a dictionary is used as a return value somewhere) can now affect the code generation for a dictionary and hence whether the relevant binding file should be regenerated. Since these changes can happen in any .webidl file, we need to check for them. We can't track this via the dependency set on the dictionary itself, because that would not notice new uses being added.
