security: Refactoring creation of SecPublicInfo and SecTpm during KeyChain creation

The objective of this refactoring is to allow KeyChains with custom PIB
and TPM.  As of this commit, KeyChain no longer hard-codes PIB and TPM
instance creation.  Instead, creation is delegated to factory functions,
which need to be statically registered, e.g., using
`NDN_CXX_KEYCHAIN_REGISTER_PIB` and `NDN_CXX_KEYCHAIN_REGISTER_TPM`
macros.
