Refactor to use urfave/cli/v2 (#25959)
Replace #10912

And there are many new tests to cover the CLI behavior

There were some concerns about the "option order in hook scripts"
(https://github.com/go-gitea/gitea/pull/10912#issuecomment-1137543314),
it's not a problem now. Because the hook script uses `/gitea hook
--config=/app.ini pre-receive` format. The "config" is a global option,
it can appear anywhere.

## ⚠️ BREAKING ⚠️

This PR does it best to avoid breaking anything. The major changes are:

* `gitea` itself won't accept web's options: `--install-port` / `--pid`
/ `--port` / `--quiet` / `--verbose` .... They are `web` sub-command's
options.
    * Use `./gitea web --pid ....` instead
* `./gitea` can still run the `web` sub-command as shorthand, with
default options
* The sub-command's options must follow the sub-command
* Before: `./gitea --sub-opt subcmd` might equal to `./gitea subcmd
--sub-opt` (well, might not ...)
    * After: only `./gitea subcmd --sub-opt` could be used
    * The global options like `--config` are not affected

`backport`
==========

`backport` is a command to help create backports of PRs. It backports a
provided PR from main on to a released version.

It will create a backport branch, cherry-pick the PR's merge commit, adjust
the commit message and then push this back up to your fork's remote.

The default version will read from `docs/config.yml`. You can override this
using the option `--version`.

The upstream branches will be fetched, using the remote `origin`. This can
be overrided using `--upstream`, and fetching can be avoided using
`--no-fetch`.

By default the branch created will be called `backport-$PR-$VERSION`. You
can override this using the option `--backport-branch`. This branch will
be created from `--release-branch` which is `release/$(VERSION)`
by default and will be pulled from `$(UPSTREAM)`.

The merge-commit as determined by the github API will be used as the SHA to
cherry-pick. You can override this using `--cherry-pick`.

The commit message will be amended to add the `Backport` header.
`--no-amend-message` can be set to stop this from happening.

If cherry-pick is successful the backported branch will be pushed up to your
fork using your remote. These will be determined using `git remote -v`. You
can set your fork name using `--fork-user` and your remote name using
`--remote`. You can avoid pushing using `--no-push`.

If the push is successful, `xdg-open` will be called to open a backport url.
You can stop this using `--no-xdg-open`.
