Add basic handling for entitlement keys in a license.

Browse Source 
Merge from Widevine repo of http://go/wvgerrit/41834

Key rotation is not yet supported.

The key statuses are updated from a license. The
mechanism expects content keys tro come in a license.
For entitlement licenses, the content keys come in the
init_data.

This code does not yet support the key rotation event.
(A new pssh with wrapped keys is a passed to the cdm)
The policy engine/key status mechanism needs to be
updated to handle updated from the init_data.

For now, the cdm builds a license with a key container
with the content keys and used that to call
PolicyEngine::SetLicense to setup the policy engine
and key statuses.
