revsets: stop jj parsing br as a git_ref refs/heads/br

Browse source 
Use `br@git` instead.

Before, if there is not a local branch `br`, jj tried to resolve
it as a git ref `refs/heads/br`. Unchanged from before, `br` can
still be resolved as a tag `refs/tag/br`.

* `jj debug completion`, `jj debug mangen` and `jj debug config-schema` have
been moved from `jj debug` to `jj util`.
* `jj` will no longer parse `br` as a git_ref `refs/heads/br` when a branch `br`
does not exist but the git_ref does (this is rare). Use `br@git` instead.
### New features
* `jj git push --deleted` will remove all locally deleted branches from the remote.
