More plumbing for fallback configs

This CL adds a 'fallback_config_' member to QuicCryptoServerConfig along with plumbing for setting it and passing it around.  Nobody sets it to anything other than nullptr yet - a subsequent flag-protected change will modify GFE to set it.

gfe-relnote: More no-op-refactoring, not flag-protected.
