ci: rewrite bump check and respect semver

### What does this PR try to resolve?

This ports `ci/validate-version-bump.sh` and #12200 to the new xtask `bump-check`. It also adds the ability to set the correct baseline revision when checking version bump. That is, it fixes #12347.

In addition, this integrates the community tool `cargo-semver-checks`. SemVer violation can now be detected earlier.

### How should we test and review this PR?

This PR extracts the registry query part from `xtask-unpublished` and removes other pars. I don't feel like we need it in the short term.

For how it works, please the check doc comment in each function.

One concern is that this check is still a required job for bors. I believe `@obi1kenobi` is quite responsive and willing to help if there is something wrong. So, waiting for an upstream fix won't be a problem for cargo. Also as a good citizen in the community, we can always contribute back.
(Take it easy `@obi1kenobi,` don't be stressed out 🙂)
