Subject: meson: Move all code generation scripts to utils/codegen/

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/.
