Add OEMCrypto v12 functions to profiler

This CL adds the new oemcrypto v12 functions for provision 3.0 to the
list of profiler functions.

OEMCrypto v12 adapter

This CL updates the oemcrypto dynamic and static adpaters to include
oemcrypto v12 funtionality.  It adds the three new Provisioning 3.0
functions.

It also adds code in the initialization routine to null out all of
the function pointers if any of them fail to load.  It is better to
fall back to level 3 than to use an inconsistent level 1.
