Use either spelling of AllocateSecureBuffer in dynamic adapter

Browse Source 
Merge from Widevine repo of http://go/wvgerrit/121883

There was a problem in the v16.3 header that did not rename
OEMCrypto_AllocateSecureBuffer to _oecc109 or
OEMCrypto_FreeSecureBuffer to _oecc110. These functions are only used
in testing.

This changes the dynamic adapter to accept either name for those
functions.
