Allow variable length connection IDs in v99
This CL enables the use of QUIC variable length connection IDs (VLCIDs) in v99. It also relaxes some checks when VLCIDs are enabled, and fixes tests that were relying on this. This CL also fixes QuicFramerTest.MissingDiversificationNonce as this work uncovered that the test was failure to parse headers because the headers were wrong, instead of testing for missing diversification nonces.
