RFR: 8276095: ciReplay: replay failure due to incomplete ciMethodData information

Thu Nov 11 03:36:51 UTC 2021

The replay data was missing MethodData::_invocation_counter.  Adding it seems to fix the problem.  @rwestrel please verify if it works for you.  Also, with this change:
1. added a version number to the replay file
2. removed unnused ci fields
3. corrected comment in TestLambdas.java
