Core CDM: Remove usage info as a run-time type.

Browse Source 
[ Merge of http://go/wvgerrit/159221 ]

This CL modifies how usage entry info is tracked internally by the
CDM at run time.  It removes the different "storage types" that
entries represent (license or usage info), and instead it contains
only the information associated with license types.  The presences
of a key-set-id allows the UsageTableHeader to determine if the
entry slot is currently being used, or if it can be treated as
unoccupied.

By removing this different type, it completely prevents the CDM and
its tests from using "usage-info" type entries.  This required
significant updates to the UsageTableHeader tests.

Additionally, several of the variable names within the usage table
have been simplified and shortened to reflect their new meanings.

Bug: 242289743
Test: run_x86_64_tests and usage_table_header_unittest
