Add Duration Use Case integration tests

Cherry pick from http://go/wvgerrit/102986, rvc-dev branch of
http://go/wvgerrit/105825, rvc-widevine-release of http://go/ag/12561661

This CL adds several integration tests that match the duration use
cases. The test classes are designed for the core cdm, but the test
cases match those found in oemcrypto/odk/test/odk_timer_test.cpp.

See this document for a list of use cases:
libwvdrmengine/docs/License_Duration_and_Renewal.pdf

Test: Ran the tests against v16 OEMCrypto. Some fail against v15.
