Corrections for big usage table support in L3

Browse Source 
[ Merge of http://go/wvgerrit/26421 ]

* Corrects usage_table_header lifetime management. Earlier the
  UsageTableHeader class was a singleton tied to the CdmEngine lifetime.
  With SPOIDs there might be multiple concurrent CdmEngine objects.
  The UsageTableHeader class is now associated with OEMCrypto
  lifetime. There are two UsageTableHeader objects one for each L1 and L3.
  These get allocated/deallocated on OEMCrypto Initialization/Termination
  respectively.
* UsageTableHeader requires OEMCrypto, file read/writes and
  metric gathering to perform its required functionality. Because of the
  lifetime changes, CryptoSession, DeviceFiles and MetricsGroup objects
  need to passed to the methods rather than at Creation time.
* Miscellaneous fixes, when moving or deleteing entries.
* Adds usage_table_header_unittests.
* Addresses failures with request_license_test with secure stop in L3.
