Use Inheritence for OEMCrypto Mock Properties

Browse Source 
Merge from Widevine repo of http://go/wvgerrit/24728

We use compiler options to set different properties in the oemcrypto
mock.  With this CL, we define a base class that has default
properties.  All other variants need only define the properties that
they change.
