feat(workspaces): initial pass at workspace permission utility

[florkbr]

Description

Adds workspace permissions utility hook and ties into the managed selector component.

• There is still and issue where PF does not currently support disabling tree view list items (nor gives us access to the underlying component). See Tree View - allow for more control of underlying Tree View List Items patternfly/patternfly-react#11893.
• This also does not yet disable an entire sub-tree if no nodes are accessible.

Summary by Sourcery

Add a workspace permissions utility and integrate it into the ManagedSelector to filter and disable unauthorized workspace entries

Reviewer's Guide

This PR introduces a workspace permissions utility hook and integrates it into the ManagedSelector component by extending the data fetcher and tree builder to conditionally disable inaccessible workspaces based on user permissions.
