Ryan: this is the first CL that I pulled out of
https://codereview.chromium.org/1579063002/ ("Implement a skeleton version of
Expect CT reports"). This one simply renames CertPolicyEnforcer to
CTPolicyEnforcer.

LGTM

Originally I had hoped that CertPolicyEnforcer would be able to encapsulate
other policies relevant for chain building (such as SHA-1 or RSA-1024-bit
policies), but in order to safely do that, we need to run it within the context
of the CertVerifyProc, which has a whole host of complexities regarding
threading and lifetime management (has to be entirely thread-safe and either
ref-counted or forever-living, both with their tradeoffs)

As such, I'm totally supportive of just making this class relevant for CT and
if/when we want to push embedder-specified policies down that affect chain
building, to do so in a class dedicated for that purpose.

(Just documenting why a batch rename is happening)
