Don't move project repository/attachments when using hashed storage

Closes #40289

See merge request gitlab-org/gitlab-ce!15479

Clean up schema of the "merge_requests" table

Closes #31825

See merge request gitlab-org/gitlab-ce!15377

Resolve "`master` is broken due to `static-analysis`"

Closes #40335

See merge request gitlab-org/gitlab-ce!15481

When a project is using hashed storage, the repositories and
attachments wouldn't be saved on disk using the `full_path`. So the
migration would not do anything.

However: best to just skip moving when hashed storage is enabled.

Restrict update column in batches for large tables

See merge request gitlab-org/gitlab-ce!15458

Conflicts used to take a `Repository` and pass that to
`Gitlab::Highlight.highlight`, which would call `#gitattribute` on the
repository. Now they use a `Gitlab::Git::Repository`, which didn't have that
method defined - but defining it on `Gitlab::Git::Repository` does make it
available on `Repository` through `method_missing`, so we can do that and both
cases will work.

Improved the design of the changed files dropdown

Closes #36687

See merge request gitlab-org/gitlab-ce!15367

add_column_with_default is implemented in terms of update_column_in_batches, but
update_column_in_batches can be used independently. Neither of these should be
used on the specified large tables, because they will cause issues on large
instances like GitLab.com.

This also ignores the cop for all existing migrations, renaming
AddColumnWithDefaultToLargeTable where appropriate.
