Rename oemcrypto's CryptoEngine configuration functions.

Merge from Widevine repo of http://go/wvgerrit/22797

CryptoEngine has a number of functions that return constants that
control the configuration of mock OEMCrypto.  Give all the functions
a common prefix (config_) so their intent is more clear.
