Disable clang/eslint in front_end/generated

This CL disables formatting within the `generated` directory, which is
all code that is programatically generated. Previously we disabled
eslint for `protocol.ts`, but now we are being consistent and disabling
it (and clang) for all files.

I also re-generated the files in the generated folder, so we avoid any
confusion if/when the generated scripts get re-run and suddenly the
format drastically changes.
