[ Merge of http://go/wvgerrit/93838 ] Some more rework of policy engine/policy timers code to support timer and clock value handling introduced by OEMCrypto v16. Changes are * renamed methods to include rental duration since policies for v16 use rental and playback duration for all licenses. Previously rental and playback durations enforced timing for persistent licenses and license duration was used for streaming licenses. * Moved some common code to the base PolicyTimer class from PolicyTimerV15. * Corrected data member naming (policy_timers -> policy_timers_) * Updated comments Bug: 139372190 Test: Android WV unit/integration tests Change-Id: Id925ddcc14608a8500f30c2c68486d91608a9abe
