Jon Ross-Perkins 04d534abee Remove the no_prelude directory, using --no-prelude-import directly (#5607) 
People seemed receptive [on
#toolchain](https://discord.com/channels/655572317891461132/655578254970716160/1379196447827689553),
so proceeding.

For the two name conflicts, I've set it up so that there's a
"foo.carbon" and "foo_with_prelude.carbon", to indicate that the
no-prelude approach is preferred (with a shorter name).

Note min_prelude will require a little more work/thought, I want to
avoid adding `--custom-core` etc.
