IVGCVSW-5964 Removing some remaining boost utility usages from tests.

* Adding a basic PredicateResult class to replace
  boost::test_tools::predicate_result
* Replacing all uses of boost::test_tools::predicate_result with
  the new armnn::PredicateResult class
* Replacing use of boost::test_tools::output_test_stream output
  with std::ostringstream in ProfilerTests.cpp
