Get-AzADApplication -OwnedApplication only works when a User Principal is signed in

### Description

When I issue `Get-AzAdApplication -OwnedApplication` when I'm signed in as a Service Principal, I get the following error:
`/me request is only valid with delegated authentication flow.` This means it's not possible to for example use this command in a script that runs under a Managed Identity.

The reason this error occurs is because the cmdlet unconditionally uses the URI `https://graph.microsoft.com/v1.0/me/ownedObjects/$/Microsoft.Graph.Application`, which indeed will not work when a Service Principal is logged in.

Instead the cmdlet should use the account context to check whether a Service Principal is logged in, and if so the cmdlet should extract the appId from the context and use the URI `https://graph.microsoft.com/v1.0/servicePrincipals(appId='{appId}')/ownedObjects/microsoft.graph.application?$count=true` (with a header `ConsistencyLevel: eventual` to make it an [advanced query](https://learn.microsoft.com/en-us/graph/aad-advanced-queries?tabs=http)).

This will result in the same information provided by the `/me` URI, but will work for Service Principals.
