  Log Message:
  -----------
  Trusted Types policy name CSP logic incorrectly handles multiple directives
https://bugs.webkit.org/show_bug.cgi?id=286917

Reviewed by Tim Nguyen.

Previously the violation disposition could get incorrectly moved back to "Allowed" by a later
CSP header. This patch updates the logic to correct this.

Now once a header disallows a policy name it stays disallowed.
