After somebody else rebased and force-pushed a stack of branches, every
branch of the stack has to be brought back to its upstream, and pressing
`f` on them one by one is as tedious as the checking out and pulling it
replaces.
Let `f` work on a range selection. The upstream branches are fetched with
one `git fetch` per remote, and the branches that aren't checked out
anywhere move in a single `git update-ref` call. All the selected
branches are looked at before any of them is moved, so a branch that has
to be refused leaves the others alone rather than updating the stack
halfway.

When somebody else rebases a branch and force-pushes it, the local
branch is left diverged from it, so `f` refuses to touch it. To get back
in sync, the branch has to be checked out and pulled, and for a stack of
branches that means doing it once per branch.
Such a branch has none of its own work in it, though: the commits it is
ahead by are the old versions of the ones that are now on the remote
branch. So when the branch has diverged and none of the commits it is
ahead by is ours, reset it to its upstream instead of refusing. This is
the same state that checking the branch out and pulling it would produce,
as rebase drops commits that the upstream already has.
A branch that isn't checked out anywhere is reset with the same
`git update-ref` that a fast-forward uses. One that is checked out
somewhere is reset with `git reset --keep`, and only when that worktree
has no changes to tracked files, so that the files under the user's feet
change no more than they have to. `--keep` also refuses to overwrite an
untracked file that the reset would bring in, which `--hard` would do
silently.

After rebasing a stack of branches, every branch of the stack has to be
force-pushed, and so far the only way to do that in lazygit was to check
out each branch in turn and push it. For a stack of a dozen branches
that is a lot of work for a routine task.
When the current branch is pushed and there are branches below it in the
stack that have commits to push, show a menu that offers to push them
along with it. The menu lists the branches and how far each of them has
diverged from its remote branch, so that the user can see what is about
to happen. It doesn't show where each branch goes; the branches panel
doesn't show that for a normal push either. Pushing only the current
branch is the second entry. If any of the branches has diverged from its
remote branch, a single confirmation covers force-pushing all of them.
A branch is offered if its tip is a commit of the current branch that
isn't merged yet, it has an upstream that is stored locally, that
upstream is not gone, and it is ahead of its push destination. Branches
without an upstream are left out because a branch that was never pushed
can't be told apart from one that is meant to stay local. A branch that
is only behind is left out because pushing it would move the remote
branch back to an older commit; the lease doesn't catch that when the
remote-tracking branch is up to date.
Each branch is pushed to where `git push` would push it if it were
checked out, using the destination git reports in the %(push) field.
This honors push.default, remote.pushDefault and
branch.<name>.pushRemote without lazygit having to interpret them.
Branches going to the same remote are pushed in one command, with
--force-with-lease when the user confirmed force-pushing; the lease
checks each ref against its remote-tracking branch, so a coworker's
unseen push is still rejected. The current branch joins that command
when its remote-tracking branch is stored locally. Otherwise it needs a
plain push first, for example with --set-upstream, and that option
would apply to every refspec of a combined command; so in that case it
is pushed on its own as before, and the other branches follow in a
second command.
Pushing the current branch on its own still runs a bare `git push`, so
users who rely on push.default or remote.<name>.push for it see no
change. The push is non-atomic, as git defaults to; if one branch's
lease fails, the others still go through and the error names the one to
look at.

Use Equals instead of Contains for asserting the status view content. This
solves the problem that we might assert Contains("↓2 repo"), but what it really
shows is "↑1↓2 repo", and the test still succeeds. At best this is confusing.
Also, this way we don't have to use the awkward DoesNotContain to check that it
really doesn't show a checkmark.
To do this, we need to fix two whitespace problems:
- there was always a space at the end for no reason. Simply remove it. It was
added in efb51eee96, but from looking at that diff it seems it was added
accidentally.
- there was a space at the beginning if the branch status was empty. This is
actually a cosmetic problem, for branches without a status the text was
indented by once space. Change this so that the space is added conditionally.
It's a bit awkward that we have to use Decolorise here, but this will go away
again later in this branch.
