ledger-api-test-tool: Remove retired tests. (#12535)

CHANGELOG_BEGIN
- [Ledger API Test Tool] The retired test suites, ``LotsOfPartiesIT``
  and ``TransactionScaleIT``, have been removed in favor of more
  targeted benchmarking tests. If you are actively including these tests
  in your test run, you will need to remove them. These tests are
  disabled by default so it is likely that no change will be needed.
