 Description   

Use the FCV mechanisms to guard the feature of unlimited index key. Things to remove include:

  1. The hardcoded size limits in the SortedDataInterface of each storage engine (wiredtiger_index.cpp, mobile_index.cpp, ephemeral_for_test_btree_impl.cpp)
  2. The hardcoded size limit for KeyString (key_string.h)
  3. The hardcoded size limit in index validations (record_store_validate_adaptor.cpp)
