We have multiple code generation scripts in utils/, mixed with other miscellaneous utilities, as well as a larger code base based on mojom in utils/ipc/. To make code sharing easier between the generator scripts, without creating a mess in the utils/ directory, move all the code generation code to utils/codegen/.
