feat: Add visibility checks for installation types (#10773)

This pull request includes multiple changes to the sidebar and route
metas to configure visibility of features on the dashboard.

Here's a summary of the changes

1. Added `installationTypes`, field to routes `meta`, this works along
side `permissions` and `featureFlags`
This allows us to decide weather a particular feature is accessible on a
particular type. For instance, the Billing pages should only be
available on Cloud
2. Updated `usePolicy` and `policy.vue` to use the new
`installationTypes` config
3. Updated Sidebar related components to remove `showOnlyOnCloud` to use
the new policy updates.
