Get System ID From OEM Cert

Browse Source 
(This is a merge from http://go/wvgerrit/30220)

Previously, extracting the system ID was only supported on Keybox-based
systems. This patch adds support for extracting the system ID from the
OEM Certificate chain on Provisioning 3.0 devices. This is done by
getting the Widevine intermediate cert from the chain, finding the
Widevine System ID extension in that cert, and extracting the value.

The code that does the extraction is separate from any code that calls
OEMCrypto so that it can be unit-tested in isolation. This patch adds a
crypto_session_unittest test to do this unit-testing.

Test: crypto_session_unittest
