Re-land: Add download_file_types.proto with ascii->binary conversion, as a resource.
This is a revert of the revert https://codereview.chromium.org/1881273002/
Added: Missing Python path, on some bots.
Orig desc: We'll maintain an ASCII version of the data in the repo, and build
the binary version as a Resource at build time. The data will later be
updated at runtime.
