This reverts commit 24a0601d5b.
Reason for revert: This breaks the flutter build because flutter has
a build target producing the same "gen/frontend_server.dart.snapshot" file and is therefore conflicting.
See e.g. head-head-head bot failure:
https://ci.chromium.org/p/dart/builders/ci.sandbox/flutter-engine-linux/9747
Original change's description:
> Create the frontend_server snapshot as a part of the sdk
>
> This will allow us to use it from webdev, as it now supports DDC output.
