Move functionality to policy_timer.

Browse Source 
[ Merge of http://go/wvgerrit/164277 ]

No functional changes are made in this CL. policy_timer_v16 and
policy_timer_v15 derive from policy_timer. We have removed
support for OEMCrypto v15. policy_timer_v15 has also been removed.

This allows us to move functionality from policy_timer_v16
to policy_timer class. This will ease subsequent renew on
license load functionality.
