Add ability to template dynamic dialogs.

[toxaq]

###Defect Fixes
Solves #9235 and #7603

Backward compatible, simply set config.minimal to true and you can use dialog templates as follows:

<p-dialog-title>
  <h3>Example title</h3>
</p-dialog-title>
<p-dialog-content><p>example content here</p></p-dialog-content>
<p-dialog-actions>
  <button (click)="cancel()">Cancel</button>
  <button (click)="delete()">Delete</button>
</p-dialog-actions>

The PR has been closed without a comment? Does the PR not meet your requirements or are you working on a different solution to the problem?

@MetroMarv I closed it because after receiving zero feedback on my submission, and realising that the original issues are from 2019 and 2020 respectively, it was clear this is going nowhere. I've decided to change the UI library I've adopted and so won't be rebasing this against an ever moving codebase.

[MetroMarv]

Sorry @toxaq I didn't realize it was you as the PR creator who closed the PR.
