Add tags school association

[betsyecastro]

• Implements changes made in the school html element research_profile[schools][] in the research student application form as proposed in #122.
• Changes in the Tags Modal Livewire component include:
  • Change the type of the tags_type property from string to array to use as an array of multiple elements with the format: TagType\SchoolShortName (i.e. [App\Student\BBS, App\Student\ECS]) to filter the tags shown in the modal based on the school selection.
  • Add the include_view property (string) to pass a blade.js file path with the js code to handle the interaction of removing/adding elements to the array tags_type and refresh the component.
  • Change the sync_tags method to Loops through tags_type to sync tags.
• Display message to select the school to list the tags available when no school selection has been made.

I've merged these changes into PR #122 instead, so that it was easier to resolve any merge conflicts.
