Rollup merge of #139520 - jieyouxu:compiletest-maintenance-1, r=lqd

compiletest maintenance: sort deps and drop dep on `anyhow`

Two changes:

1. Sort compiletest deps alphabetically because it was annoying me (harder to quickly glance what deps compiletest is using).
2. Drop dependency on `anyhow`. There's only one usage of `anyhow`, which is for `with_context` on sth that would immediately panic anyway.
