Describe the problem that is addressed by this PR

This PR makes the following changes to the Identity library:

1. Migrates DeviceCodeCredential to the MSALClient flow
2. Skips silent authentication for client credential based flows
3. Allows passing disableAutomaticAuthentication as an option param instead of during client construction

The reason this is important and exciting is because DeviceCodeCredential is the first PublicClientApplication based flow that is being migrated to MSALClient!
