Introduce UsageTableHeader class

Browse Source 
[ Merge of http://go/wvgerrit/23820 ]

The UsageTableHeader class is a singleton that CDM sessions will share.
A separate object will be created for each security level. The class
synchronizes access to usage table header and associated data-structures
and controls when they are read in or written out to non-secure persistent
storage. Upgrades from a fixed size usage table (supported by previous
versions of the OEMCrypto API v9-12) are handled by this class.
