Rollup merge of #113068 - clubby789:bootstrap-user-to-dist, r=jyn514

bootstrap: rename 'user' profile to 'dist'

Fixes #112074

Unfortunately a big chunk of the diff is adding `PartialEq/Eq/Debug` impls so we can `assert_eq` but I think better to have them in the long run.
For back compat, ensure `"maintainer"`, `"user"` and `"dist"` are all parsed as `Profile::Dist`.
