MDEV-5244: Make extended_keys=ON by default in 10.0

- Change the default flag value to ON.
- Update the testcases to be run extended_keys=ON:
  = trivial test result updates
  = If extended_keys setting makes a difference for a testcase, run the testcase 
    with extended_keys=off. There were only a few such cases
- Update to vcol_select_innodb looks like a worse plan but it will be gone in 10.0.
