Resolve "Remove routes that we do not use anymore"

## What does this MR do?

> I tried to clean up the routes as mentioned in #14584
I used the following script and manually verified the changes: https://gist.github.com/strzibny/4ccbda7dcf67ef6719dcb047014e1ea7
After this patch, the script still gives me the following routes:
Unused routes (7): oauth/authorizations#show doorkeeper/tokens#create doorkeeper/tokens#revoke oauth/applications#edit oauth/applications#show doorkeeper/token_info#show omniauth_callbacks#(?-mix:(?!))
Here is a relevant code from doorkeeper on drawing these routes: https://github.com/doorkeeper-gem/doorkeeper/blob/5ea4575863781940fe6996692c6b41f2ad71d90e/lib/doorkeeper/rails/routes.rb#L25

## What are the relevant issue numbers?

Closes #14584.

NotesHelper#note_editable? and ProjectTeam#human_max_access currently
take about 16% of the load time of an issue page. This MR preloads
the maximum access level of users for all notes in issues and merge
requests with several queries instead of one per user and caches
the result in RequestStore.

Return request profiling info when a header is passed

## What does this MR do?

Fix a bug where forking a project from a repository storage to another would fail

## What does this MR do?

Fix a bug where forking a project from a repository storage to another would fail.

## Are there points in the code the reviewer needs to double check?

No

## Why was this MR needed?

If you have a project in storage_a, change the default storage to storage_b, and attempt to fork said project, the import will fail.

Show release notes in tag list

## What does this MR do?

Two things in one! Ensure that a tag's message having an invalid UTF-8 byte sequence doesn't cause a 500, like at: https://gitlab.com/bitcubate/node/tags?page=9 (The problem tag is https://gitlab.com/bitcubate/node/tags/v0.1.0)

Also ensure that the release notes are actually shown on the tag index, like they are supposed to.

## Are there points in the code the reviewer needs to double check?

There's not much, so all of it.

## Why was this MR needed?

The tags index was broken in two ways.

## What are the relevant issue numbers?

Closes #20233 but does more than that.

A release's tag reference is just the name of the tag, not the entire
tag object.

This also fixes the tags index if a tag's message contains non-UTF8 byte
sequences.

Rescue Rugged::OSError (lock exists) when creating references.

## What does this MR do?

Rescue an exception on concurrent scenarios. I was able to create a spec for this, because if you create the lock file before trying to create the reference the reference is created without a problem and the lock file is removed. So IMHO there is a race condition where more than one process is trying to create the same reference at the same time raising the exception, so I just added the patch without specs.

```ruby
    it "attempting to call keep_around when exists a lock does not fail" do
      ref = repository.send(:keep_around_ref_name, sample_commit.id)
      path = File.join(repository.path, ref)
      lock_path = "#{path}.lock"

      FileUtils.mkdir_p(path)
      File.open(lock_path, 'w') { |f| f.write('') }

      begin
        # No exception is raised because the lock file is removed at some point in the process
        repository.keep_around(sample_commit.id)
      ensure
        File.delete(path)
        File.delete(lock_path)
      end
    end
```

Fix expand all diffs button in compare view

## What does this MR do?

Fix the expand all diffs button in compare view.

## Are there points in the code the reviewer needs to double check?

Don't think so.

## Why was this MR needed?

We can't reuse the existing value of the format parameter, because on
the merge request page that's 'json', so the link would go to a JSON
file. We can't set it to HTML, because that adds '.html' to the URL, which
breaks the compare view (and looks bad). Setting it to `nil` uses the
default format, which in all of these cases is HTML anyway.


## What are the relevant issue numbers?

Closes #20241.
