Add usage support query method

Browse Source 
[ Merge of http://go/wvgerrit/23522 ]

A helper method has been added to CryptoSession to determine whether the
TEE supports usage tables, usage table headers+entries or does not
provide any support for persistent licenses.

In addition
* CryptoSession now supports deletion of multiple
  usage entries rather than a single one.
* Typedefs have been added for usage table headers and entries
