rails: disable asset pipeline.

Disable the assets pipeline (Sprockets). Sprockets errors out now after
upgrading to Sprockets 4 because of missing config files. We don't use
it any more after switching to Webpack, so we can disable it entirely.

Also disable a few more Rails features that we don't use (ActiveStorage,
ActionCable, ActionMailbox, ActionText).
