API: Share projects only with groups current_user can access

Aims to address the issues here: https://gitlab.com/gitlab-org/gitlab-ce/issues/23004

* Projects can be shared with non-existent groups
* Projects can be shared with groups that the current user does not have access to read

Concerns:

The new implementation of the API endpoint allows projects to be shared with a larger range of groups than can be done via the web UI.

The form for sharing a project with a group uses the following API endpoint to index the available groups: https://gitlab.com/gitlab-org/gitlab-ce/blob/494269fc92f61098ee6bd635a0426129ce2c5456/lib/api/groups.rb#L17. The groups indexed in the web form will only be those groups that the user is currently a member of.

The new implementation allows projects to be shared with any group that the authenticated user has access to view. This widens the range of groups to those that are public and internal.

Fix export project file permissions issue

Fixes security concerns of https://gitlab.com/gitlab-org/gitlab-ce/issues/22757

I have just added the permissions 0700 to the creation of any of the export paths, as @jacobvosmaer suggested in https://gitlab.com/gitlab-org/gitlab-ce/issues/22757#note_16197616

After this has fixed, it could take up to 24 hours in the worse case scenario for old archives to be completely safe - This is the time `ImportExportProjectCleanupWorker` may take to remove the folders. The temporary folders will be 0700 straight away for new installations.

Prevent claiming associated model IDs via import

On the import side, we should be careful not to use any IDs as part of the JSON file that could have been manipulated.

Part of https://gitlab.com/gitlab-org/gitlab-ce/issues/20821

Things we already do (__before__ this fix):

1. Remove all primary keys
1. **Always** reassign some of the foreign keys, such as ALL project IDs and user IDs (so it would be difficult to impersonate or try to gain access to another project)
1. Ignore/reject attributes that do not exist in the model
1. If someone reassigns a foreign key `submodel_id`, and that object has another json as the submodel, the new submodel will reassign the `submodel_id` to the newly created submodel ID.

Things we should do:

1. Remove/nullify any other foreign keys that we don't reassign (checked this, and there aren't many, fortunately. In fact, I don't think much harm can be done at all - at the moment).

Fix project deletion when feature visibility is set to private

Projects that are destroyed are put in the pending_delete state.
The ProjectDestroyWorker checks whether the current user has
access, but since the ProjectFeature class uses the default scope
of the Project, it will not be able to find the right project.

This was a regression in 8.12 that caused the following stack trace:

```
NoMethodError: undefined method `team' for nil:NilClass

Changed compare dropdowns to dropdowns with search input

## What does this MR do?

This changes the compare dropdowns from text inputs, that when clicked, open a dropdown of branches/tags to dropdowns that have a dropdown toggle and an isolated search input.

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

## Why was this MR needed?

This was needed to fix the poor UX highlighted in #22221, where opening the dropdown showed an initially filtered set of results because the dropdown toggle was the dropdown filter itself. The compare page is always loaded with `master` as each branch/tag selection, so when opening the dropdown, it would only show results matching `master`.

Do not regenerate the `lfs_token` every time `git-lfs-authenticate` is called

## What does this MR do?

 Do not regenerate the `lfs_token` every time `git-lfs-authenticate` is called, instead return the saved token if one is present.

This was causing a lot of 401s, leading to 403s, as state in #22527

As it turns out, when pushing a lot of LFS objects, the LFS client was calling `git-lfs-authenticate` in the middle of the request again. This caused the `lfs_token` to be regenerated. The problem lies in that the LFS client was not aware of this change, and was still using the old token. This caused all subsequent requests to fail with a 401 error.

Since HTTP Auth is protected by Rack Attack, this 401s where immediately flagged and resulted in the IP of the user being banned. 

With this change, GitLab returns the value stored in Redis, if one is present, thus if the LFS client calls `git-lfs-authenticate` again during the request, the auth header will remain unchanged, allowing all subsequent requests to continue without issues.

Fixes #22527
