LibTest: Expand test result bool to a TestResult
This will be used in the randomized tests a lot more than it is in the unit tests / benchmarks; randomized tests will run the test function multiple times, check the result and optionally start shrinking the failing input. Generators will also be able to fail, resulting in some of the new TestResult variants.
