L1 System Lowered to L3 Still Requires Secure Decoders

Browse Source 
Merge of https://widevine-internal-review.googlesource.com/#/c/8263
from the Widevine repo.

Changes the behavior of requiresSecureDecoderComponent() to query the
session for whether a lowered security level has been requested
before querying the system to see what its default security level is.

As part of this, we added a new QuerySessionStatus() method to the
CDM that gets status info on a session-specific level, such as the
effective security level of a session.
