      Description:

      Remove any documentation about the 1KB index key size limit.

      Engineering Ticket 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)

      Scope of changes

      Add blurb that only for 4.2 fcv or greater.
