Enable usage reporting

Browse Source 
[ Merge from Widevine CDM repo of
  https://widevine-internal-review.googlesource.com/#/c/10171/ and
  https://widevine-internal-review.googlesource.com/#/c/10172/ ]

Updated license_protocol.proto from constituent protos in google3

These changes make use of OEMCrypto v9 changes to support usage reporting.
Usage reporting may be enabled for streaming (by means of secure stops) and
offline playback by a provider session token specified in the license.

Changes include periodically updating usage information for relevant
sessions and reporting and releasing usage information as needed.

The CDM has removed all references to Secure Stops. This change
updates the Android API implementation to comply.
