Update OEMCrypto documents

Browse Source

Merge from Widevine repo of http://go/wvgerrit/97763

There were no function signature changes, so the API version number
did not change from 16.2. There were several grammar and spelling
errors. There were also the following corrections:

1. The description of OEMCrypto_LoadProvisioning now says that devices
with a keybox use keys derived from the keybox device key, and devices
using Provisioning 3.0 use keys derived from the session key. The
description was previously reversed.

2. The function OEMCrypto_SupportedPatterns is no longer
discussed. This function was never fully defined.

3. The function OEMCrypto_LoadRenewal no longer says that keys and key
control blocks should be verified. This is because the function
OEMCrypto_LoadRenewal processes a message with no key control
block. It should update timers for the entire license.

Test: doc and comment change only
