We currently have several specific elements cloaked to prevent
flashing when using startup.css. This MR introduces a generic
class which can be applied to any element to achieve the same.

Here we apply it to the mobile top nav overlay to fix broken
rendering in certain race/network conditions.

We are regularly seeing
CrossDatabaseModificationAcrossUnsupportedTablesError failures when we
call
[`Plan.default`](https://gitlab.com/gitlab-org/gitlab/-/blob/ad0085ce21be8d39b7598cb124adee7c75405922/app/models/plan.rb#L13)
and/or
[`Namespace#actual_plan`](https://gitlab.com/gitlab-org/gitlab/blob/master/ee/app/models/ee/namespace.rb#L180)
because both of these methods are lazily creating records.

At present we believe this is not strictly a problem that we need to
solve since it will is likely totally OK that creating a `plans` record
in the middle of a transaction related to `ci_pipelines` is not
important to rollback. Even more these lazy creations likely never need
to be rolled back anyway so we probably don't need to push these outside
the transactions.
