Roles are missing registration type dependencies

Problem/Motivation

The "per registration type" permissions are not adding a dependency on the registration type to roles that use them. This could result in the exception RuntimeException: Adding non-existent permissions to a role is not allowed when updating roles, if a registration type is ever deleted.

Steps to reproduce

Add a new registration type. Assign per-type permissions to a role. Delete the registration type. Attempt to update the role - an exception occurs during save.

Proposed resolution

Redo the Registration permission provider to leverage the core BundlePermissionHandlerTrait which adds the required dependencies. When a registration type is deleted, the dependencies trigger removal of permissions that no longer exist from any roles that use them.
