  Enable strict decoding of NSURLProtectionSpace behind runtime flag

Reviewed by David Kilzer.

Even before rdar://107730786 is resolved, we can strictly decode NSURLProtectionSpace
by simply transforming the NSMutableDictionary serialized members to NSDictionary members
like we do with NSURLCredential.  Enable strict decoding when strictSecureDecodingForAllObjCEnabled
returns true.

I also separate the remaining non-strict-decoded ObjC classes so their strict decoding can be
enabled with straightforward changes, and annotated each one with the blocking radar.
To make the logic less cluttered, I move the lists of MessageNames to lambdas.  These changes
don't change behavior now.
