[Vue] migrate goal page link directive and add event to replace use of angularjs in html ajax code #18888

Description:

Changes:

• Migrates the piwik-goal-page-link directive to vue.
• Added an event Matomo.processDynamicHtml that is called after compileAngularComponents() is called, and use this to invoke GoalPageLink directive manually without angularjs. Ideally this workflow should be avoided but can't be as long as dataTables expect angularjs. For Matomo 5, when angularjs is removed, it might be possible to treat the twig template output as a vue template.
