Trigger a menu link rebuild for user roles and views entity operations

Problem/Motivation

This issue is a follow-up to 📌 Automated Tests: Add Functional tests for classes ExtraLinks and SearchLinks Needs review where this bug was identified when testing the Admin Toolbar Tools module.

Creating, deleting or updating a user role or a view does not get reflected immediately in the Admin Toolbar's extra links.

Steps to reproduce

[Insert]
User roles:
1 - Enable the Admin Toolbar Tools module.
2 - Add a user role at admin/people/roles/add
3 - Confirm the added role does not display in the menu links.

Views:
1 - Enable the Admin Toolbar Tools and Views modules.
2 - Add a view at admin/structure/views/add
3 - Confirm the added view does not display in the menu links.

[Delete]
Repeat the same steps with deleting a user role and a view and confirm the corresponding link still appears in menu links.

[Update]
Repeat the same steps with updating a user role and a view name/label and confirm the corresponding role and view still appear with the label before it was updated.

Proposed resolution

Add the 'user_role' and 'view' entity types to the ones currently triggering a menu link rebuild on entity operations, see:
https://git.drupalcode.org/project/admin_toolbar/-/blob/3.6.2/admin_tool...

This is already the case for the 'menu' config entity type: Whatever operation is carried on menus (create, delete or update), the changes will always immediately be reflected in the Admin Toolbar's extra menu links.
