[Feature Request] Support custom client ID

**Related command**
`az login`

**Is your feature request related to a problem? Please describe.**
Currently Azure CLI uses a fixed client ID to authenticate into AAD

https://github.com/Azure/azure-cli/blob/1d973cceb38980181eeaa45934497d2148a3e7b2/src/azure-cli-core/azure/cli/core/auth/identity.py#L22

This client ID `04b07795-8ddb-461a-bbee-02f9e1bf7b46` is a First Party Application, registered in First Party Portal.

This application is only pre-authorized for a limited set of [Microsoft Graph permissions](https://docs.microsoft.com/en-us/graph/permissions-reference). Using Azure CLI command `az rest` to call [trustFrameworkKeySet](https://docs.microsoft.com/en-us/graph/api/trustframeworkkeyset-get?view=graph-rest-beta&tabs=http) API which requires **TrustFrameworkKeySet.Read.All**, **TrustFrameworkKeySet.ReadWrite.All** will fail (https://github.com/Azure/azure-cli/issues/22755).

**Describe the solution you'd like**
Support custom client ID, so that users can create their own app in their tenant, consent to that app and let Azure CLI use that app’s client ID:

```
az login --client-id
```

**Describe alternatives you've considered**
Apply for those permissions in First Party Portal to support these APIs.
