Require Features for Android OEMCrypto

Merge from Widevine repo if http://go/wvgerrit/13781 This CL adds several unit tests that are specifically designed to test features that are required for Android CDM but not other platforms. Once this CL has been merged, future CLs will modify the main oemcrypto test file so that some tests are skipped if their features are not implemented.

+// OEMCrypto unit tests - extra tests required for Android platform.
+//
+// The Widevine CDM system can be built on many platforms, with different
+// capabilities. For example, some platforms do not require usage tables,
+// and some can have a pre-installed certificate and do not need a keybox.
+// On Android, these features are not optional.  This set of unit tests
+// verify that these features are implemented.
+//
+// In the file oemcrypto_test.cpp, the unit tests only verify correct
+// functionality for functions that are implemented.  Android devices must pass
+// unit tests in both files.
