Add a New Copy Button That Works in Modals

Closes #60988

See merge request gitlab-org/gitlab-ce!28676

This copy button manages a local instance of the Clipboard plugin
specific to it, which means it is created/destroyed on the
creation/destruction of the component. This allows it to work well in
gitlab-ui modals, as the event listeners are bound on creation of the
button.

It also allows for bindings to the `container` option of the Clipboard
plugin, which allows it to work within the focus trap set by bootstrap's
modals.

Always show "Pipelines must succeed" checkbox

Closes #57291

See merge request gitlab-org/gitlab-ce!28651

Before: the checkbox was hidden if builds were disabled.

The checkbox should not be linked to the builds feature
because they are 2 separate functionality.
